## Yet another hack to support SUN make.
##
## Let's assume 'foo' appears in DISTFILES and is not a built file.
## When building with VPATH=$(srcdir), SUN make and OSF1/Tru64 will
## rewrite 'foo' as '$(srcdir)/foo'. An attempt to install the file
## with
## cp $file $(distdir)/$file
## will thus install $(srcdir)/foo as $(distdir)/$(srcdir)/foo
## instead of $(distdir)/foo.
##
## So let's strip this leading $(srcdir)/ when it exists. (As far we
## know, only SUN make and OSF1/Tru64 make add it.) Searching whether
## the file is to be found in the source or build directory will be
## done later.
##
## In case we are _not_ using SUN or OSF1/Tru64 make, how can we be sure
## we are not stripping a legitimate filename that starts with the
## same pattern as $(srcdir)?
## Well, it can't happen without the Makefile author distributing
## something out of the distribution (which is bad). As an example,
## consider "EXTRA_DIST = ../bar". This is an issue if $srcdir is
## '..', however getting this value for srcdir is impossible:
## "EXTRA_DIST = ../bar" implies we are in a subdirectory (so '../bar'
## is within the package), hence '$srcdir' is something like
## '../../subdir'.
##
## There is more to say about files which are above the current directory,
## like '../bar' in the previous example. The OSF1/Tru64 make
## implementation can simplify filenames resulting from a VPATH lookup.
## For instance if "VPATH = ../../subdir" and '../bar' is found in that
## VPATH directory, then occurrences of '../bar' will be replaced by
## '../../bar' (instead of '../../subdir/../bar'). This obviously defeats
## any attempt to strip a leading $srcdir. Presently we have no workaround
## for this. We avoid this issue by writing "EXTRA_DIST = $(srcdir)/../bar"
## instead of "EXTRA_DIST = ../bar". This prefixing is needed only for files
## above the current directory. Fortunately, apart from auxdir files which
## can be located in .. or ../.., this situation hardly occurs in practice.
##
## Also rewrite $(top_srcdir) (which sometimes appears in DISTFILES, and can
## be absolute) by $(top_builddir) (which is always relative). $(srcdir) will
## be prepended later.

## --------------------------------------- ##
## Building various distribution flavors. ##
## --------------------------------------- ##
## Note that we don't use GNU tar's '-z' option. One reason (but not
## the only reason) is that some versions of tar (e.g., OSF1)
## interpret '-z' differently.
##
## The -o option of GNU tar used to exclude empty directories. This
## behavior was fixed in tar 1.12 (released on 1997-04-25). But older
## versions of tar are still used (for instance NetBSD 1.6.1 ships
## with tar 1.11.2). We do not do anything specific w.r.t. this
## incompatibility since packages where empty directories need to be
## present in the archive are really unusual.
##
## We order DIST_TARGETS by expected duration of the compressors,
## slowest first, for better parallelism in "make dist". Do not
## reorder DIST_ARCHIVES, users may expect gzip to be first.
##
## Traditionally, gzip prepended the contents of the GZIP environment
## variable to its arguments, and the commands below formerly used
## this by invoking 'GZIP=$(GZIP_ENV) gzip'. The GZIP environment
## variable is now considered to be obsolescent, so the commands below
## now use 'eval GZIP= gzip $(GZIP_ENV)' instead; this should work
## with both older and newer gzip implementations. The 'eval' is to
## support makefile assignments like 'GZIP_ENV = "-9 -n"' that quote
## the GZIP_ENV right-hand side because that was needed with the
## former invocation pattern.

## might cause the shell to die with "Arg list too long" (see

## Whenever $(AUTOHEADER) has run, we must make sure that
## ./config.status will rebuild config.h. The dependency from %STAMP%
## on %CONFIG_H_DEPS% (which contains config.hin) is not enough to
## express this.
##
## There are some tricky cases where this rule will build a
## config.hin which has the same timestamp as %STAMP%, in which case
## ./config.status will not be rerun (meaning that users will use an
## out-of-date config.h without knowing it). One situation where this
## can occur is the following:
## 1. the user updates some configure dependency (let's say foo.m4)
## and runs 'make';
## 2. the rebuild rules detect that a foo.m4 has changed,
## run aclocal, autoconf, automake, and then run ./config.status.
## (Note that autoheader hasn't been called yet, so ./config.status
## outputs a config.h from an obsolete config.hin);
## 3. once Makefile has been regenerated, make continues, and
## discovers that config.h is a dependency of the 'all' rule.
## Because config.h depends on stamp-h1, stamp-h1 depends on
## config.hin, and config.hin depends on aclocal.m4, make runs
## autoheader to rebuild config.hin.
## Now make ought to call ./config.status once again to rebuild
## config.h from the new config.hin, but if you have a sufficiently
## fast box, steps 2 and 3 will occur within the same second: the
## config.h/stamp-h1 generated from the outdated config.hin will have
## the same mtime as the new config.hin. Hence make will think that
## config.h is up to date.
##
## A solution is to erase %STAMP% here so that the %STAMP% rule
## is always triggered after the this one.
rm -f %STAMP%
## Autoheader has the bad habit of not changing the timestamp if
## config.hin is unchanged, which breaks Make targets. Since what
## must not changed gratuitously is config.h, which is already handled
## by config.status, there is no reason to make things complex for
## config.hin.

## We want to disable the Yacc rebuild rule when
## 1. AM_MAINTAINER_MODE is used, and
## 2. --enable-maintainer-mode is not specified, and
## 3. parser.c already exist, and
## 4. parser.y and parser.c are distributed.
## Point #3 is because "make maintainer-clean" erases parser.c, yet
## the GNU Coding Standards require that ./configure; make works even
## after that.
## Point #4 is because parsers listed in nodist_*_SOURCES are always
## built on the user's side, so it makes no sense to disable them.
##
## Points #1, #2, #3 are solved by unconditionally prefixing the rule
## with $(am__skipyacc) defined below only when needed.
##
## Point #4 requires a condition on whether parser.y/parser.c are
## distributed or not. We cannot have a generic rule that works in
## both cases, so we ensure in automake that nodist_ parsers always
## use non-generic rules.

##
## - if deps are turned off, %AMDEP% is mapped onto FALSE, and therefore

##
## - if deps are on, %AMDEP% is mapped onto AMDEP, and therefore

## other configure-time conditional.
##
## We do likewise for %FASTDEP%; this expands to an ordinary configure-time

*************************
Copyright (C) 1994-1996, 1999-2002, 2004-2016 Free Software
Foundation, Inc.
Copying and distribution of this file, with or without modification,
are permitted in any medium without royalty provided the copyright
notice and this notice are preserved. This file is offered as-is,
without warranty of any kind.
Basic Installation
==================
Briefly, the shell command './configure && make && make install'
should configure, build, and install this package. The following
more-detailed instructions are generic; see the 'README' file for
instructions specific to this package. Some packages provide this
'INSTALL' file but do not implement all of the features documented
below. The lack of an optional feature in a given package is not
necessarily a bug. More recommendations for GNU packages can be found
in *note Makefile Conventions: (standards)Makefile Conventions.
The 'configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It uses
those values to create a 'Makefile' in each directory of the package.
It may also create one or more '.h' files containing system-dependent
definitions. Finally, it creates a shell script 'config.status' that
you can run in the future to recreate the current configuration, and a
file 'config.log' containing compiler output (useful mainly for
debugging 'configure').
It can also use an optional file (typically called 'config.cache' and
enabled with '--cache-file=config.cache' or simply '-C') that saves the
results of its tests to speed up reconfiguring. Caching is disabled by
default to prevent problems with accidental use of stale cache files.
If you need to do unusual things to compile the package, please try
to figure out how 'configure' could check whether to do them, and mail
diffs or instructions to the address given in the 'README' so they can
be considered for the next release. If you are using the cache, and at
some point 'config.cache' contains results you don't want to keep, you
may remove or edit it.
The file 'configure.ac' (or 'configure.in') is used to create
'configure' by a program called 'autoconf'. You need 'configure.ac' if
you want to change it or regenerate 'configure' using a newer version of
'autoconf'.
The simplest way to compile this package is:
1. 'cd' to the directory containing the package's source code and type
'./configure' to configure the package for your system.
Running 'configure' might take a while. While running, it prints
some messages telling which features it is checking for.
2. Type 'make' to compile the package.
3. Optionally, type 'make check' to run any self-tests that come with
the package, generally using the just-built uninstalled binaries.
4. Type 'make install' to install the programs and any data files and
documentation. When installing into a prefix owned by root, it is
recommended that the package be configured and built as a regular
user, and only the 'make install' phase executed with root
privileges.
5. Optionally, type 'make installcheck' to repeat any self-tests, but
this time using the binaries in their final installed location.
This target does not install anything. Running this target as a
regular user, particularly if the prior 'make install' required
root privileges, verifies that the installation completed
correctly.
6. You can remove the program binaries and object files from the
source code directory by typing 'make clean'. To also remove the
files that 'configure' created (so you can compile the package for
a different kind of computer), type 'make distclean'. There is
also a 'make maintainer-clean' target, but that is intended mainly
for the package's developers. If you use it, you may have to get
all sorts of other programs in order to regenerate files that came
with the distribution.
7. Often, you can also type 'make uninstall' to remove the installed
files again. In practice, not all packages have tested that
uninstallation works correctly, even though it is required by the
GNU Coding Standards.
8. Some packages, particularly those that use Automake, provide 'make
distcheck', which can by used by developers to test that all other
targets like 'make install' and 'make uninstall' work correctly.
This target is generally not run by end users.
Compilers and Options
=====================
Some systems require unusual options for compilation or linking that
the 'configure' script does not know about. Run './configure --help'
for details on some of the pertinent environment variables.
You can give 'configure' initial values for configuration parameters
by setting variables in the command line or in the environment. Here is
an example:
./configure CC=c99 CFLAGS=-g LIBS=-lposix
*Note Defining Variables::, for more details.
Compiling For Multiple Architectures
====================================
You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you can use GNU 'make'. 'cd' to the
directory where you want the object files and executables to go and run
the 'configure' script. 'configure' automatically checks for the source
code in the directory that 'configure' is in and in '..'. This is known
as a "VPATH" build.
With a non-GNU 'make', it is safer to compile the package for one
architecture at a time in the source code directory. After you have
installed the package for one architecture, use 'make distclean' before
reconfiguring for another architecture.
On MacOS X 10.5 and later systems, you can create libraries and
executables that work on multiple system types--known as "fat" or
"universal" binaries--by specifying multiple '-arch' options to the
compiler but only a single '-arch' option to the preprocessor. Like
this:
./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
CPP="gcc -E" CXXCPP="g++ -E"
This is not guaranteed to produce working output in all cases, you
may have to build one architecture at a time and combine the results
using the 'lipo' tool if you have problems.
Installation Names
==================
By default, 'make install' installs the package's commands under
'/usr/local/bin', include files under '/usr/local/include', etc. You
can specify an installation prefix other than '/usr/local' by giving
'configure' the option '--prefix=PREFIX', where PREFIX must be an
absolute file name.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If you
pass the option '--exec-prefix=PREFIX' to 'configure', the package uses
PREFIX as the prefix for installing programs and libraries.
Documentation and other data files still use the regular prefix.
In addition, if you use an unusual directory layout you can give
options like '--bindir=DIR' to specify different values for particular
kinds of files. Run 'configure --help' for a list of the directories
you can set and what kinds of files go in them. In general, the default
for these options is expressed in terms of '${prefix}', so that
specifying just '--prefix' will affect all of the other directory
specifications that were not explicitly provided.
The most portable way to affect installation locations is to pass the
correct locations to 'configure'; however, many packages provide one or
both of the following shortcuts of passing variable assignments to the
'make install' command line to change installation locations without
having to reconfigure or recompile.
The first method involves providing an override variable for each
affected directory. For example, 'make install
prefix=/alternate/directory' will choose an alternate location for all
directory configuration variables that were expressed in terms of
'${prefix}'. Any directories that were specified during 'configure',
but not in terms of '${prefix}', must each be overridden at install time
for the entire installation to be relocated. The approach of makefile
variable overrides for each directory variable is required by the GNU
Coding Standards, and ideally causes no recompilation. However, some
platforms have known limitations with the semantics of shared libraries
that end up requiring recompilation when using this method, particularly
noticeable in packages that use GNU Libtool.
The second method involves providing the 'DESTDIR' variable. For
example, 'make install DESTDIR=/alternate/directory' will prepend
'/alternate/directory' before all installation names. The approach of
'DESTDIR' overrides is not required by the GNU Coding Standards, and
does not work on platforms that have drive letters. On the other hand,
it does better at avoiding recompilation issues, and works well even
when some directory options were not specified in terms of '${prefix}'
at 'configure' time.
Optional Features
=================
If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving 'configure' the
option '--program-prefix=PREFIX' or '--program-suffix=SUFFIX'.
Some packages pay attention to '--enable-FEATURE' options to
'configure', where FEATURE indicates an optional part of the package.
They may also pay attention to '--with-PACKAGE' options, where PACKAGE
is something like 'gnu-as' or 'x' (for the X Window System). The
'README' should mention any '--enable-' and '--with-' options that the
package recognizes.
For packages that use the X Window System, 'configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the 'configure' options '--x-includes=DIR' and
'--x-libraries=DIR' to specify their locations.
Some packages offer the ability to configure how verbose the
execution of 'make' will be. For these packages, running './configure
--enable-silent-rules' sets the default to minimal output, which can be
overridden with 'make V=1'; while running './configure
--disable-silent-rules' sets the default to verbose, which can be
overridden with 'make V=0'.
Particular systems
==================
On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC
is not installed, it is recommended to use the following options in
order to use an ANSI C compiler:
./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
and if that doesn't work, install pre-built binaries of GCC for HP-UX.
HP-UX 'make' updates targets which have the same time stamps as their
prerequisites, which makes it generally unusable when shipped generated
files such as 'configure' are involved. Use GNU 'make' instead.
On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
parse its '<wchar.h>' header file. The option '-nodtk' can be used as a
workaround. If GNU CC is not installed, it is therefore recommended to
try
./configure CC="cc"
and if that doesn't work, try
./configure CC="cc -nodtk"
On Solaris, don't put '/usr/ucb' early in your 'PATH'. This
directory contains several dysfunctional programs; working variants of
these programs are available in '/usr/bin'. So, if you need '/usr/ucb'
in your 'PATH', put it _after_ '/usr/bin'.
On Haiku, software installed for all users goes in '/boot/common',
not '/usr/local'. It is recommended to use the following options:
./configure --prefix=/boot/common
Specifying the System Type
==========================
There may be some features 'configure' cannot figure out
automatically, but needs to determine by the type of machine the package
will run on. Usually, assuming the package is built to be run on the
_same_ architectures, 'configure' can figure that out, but if it prints
a message saying it cannot guess the machine type, give it the
'--build=TYPE' option. TYPE can either be a short name for the system
type, such as 'sun4', or a canonical name which has the form:
CPU-COMPANY-SYSTEM
where SYSTEM can have one of these forms:
OS
KERNEL-OS
See the file 'config.sub' for the possible values of each field. If
'config.sub' isn't included in this package, then this package doesn't
need to know the machine type.
If you are _building_ compiler tools for cross-compiling, you should
use the option '--target=TYPE' to select the type of system they will
produce code for.
If you want to _use_ a cross compiler, that generates code for a
platform different from the build platform, you should specify the
"host" platform (i.e., that on which the generated programs will
eventually be run) with '--host=TYPE'.
Sharing Defaults
================
If you want to set default values for 'configure' scripts to share,
you can create a site shell script called 'config.site' that gives
default values for variables like 'CC', 'cache_file', and 'prefix'.
'configure' looks for 'PREFIX/share/config.site' if it exists, then
'PREFIX/etc/config.site' if it exists. Or, you can set the
'CONFIG_SITE' environment variable to the location of the site script.
A warning: not all 'configure' scripts look for a site script.
Defining Variables
==================
Variables not defined in a site shell script can be set in the
environment passed to 'configure'. However, some packages may run
configure again during the build, and the customized values of these
variables may be lost. In order to avoid this problem, you should set
them in the 'configure' command line, using 'VAR=value'. For example:
./configure CC=/usr/local2/bin/gcc
causes the specified 'gcc' to be used as the C compiler (unless it is
overridden in the site shell script).
Unfortunately, this technique does not work for 'CONFIG_SHELL' due to an
Autoconf limitation. Until the limitation is lifted, you can use this
workaround:
CONFIG_SHELL=/bin/bash ./configure CONFIG_SHELL=/bin/bash
'configure' Invocation
======================
'configure' recognizes the following options to control how it
operates.
'--help'
'-h'
Print a summary of all of the options to 'configure', and exit.
'--help=short'
'--help=recursive'
Print a summary of the options unique to this package's
'configure', and exit. The 'short' variant lists options used only
in the top level, while the 'recursive' variant lists options also
present in any nested packages.
'--version'
'-V'
Print the version of Autoconf used to generate the 'configure'
script, and exit.
'--cache-file=FILE'
Enable the cache: use and save the results of the tests in FILE,
traditionally 'config.cache'. FILE defaults to '/dev/null' to
disable caching.
'--config-cache'
'-C'
Alias for '--cache-file=config.cache'.
'--quiet'
'--silent'
'-q'
Do not print messages saying which checks are being made. To
suppress all normal output, redirect it to '/dev/null' (any error
messages will still be shown).
'--srcdir=DIR'
Look for the package's source code in directory DIR. Usually
'configure' can determine that directory automatically.
'--prefix=DIR'
Use DIR as the installation prefix. *note Installation Names:: for
more details, including other options available for fine-tuning the
installation locations.
'--no-create'
'-n'
Run the configure checks, but stop before creating any output
files.
'configure' also accepts some other, not widely useful, options. Run
'configure --help' for more details.

Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The GNU General Public License is a free, copyleft license for
software and other kinds of works.
The licenses for most software and other practical works are designed
to take away your freedom to share and change the works. By contrast,
the GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users. We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to
any other work released this way by its authors. You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
them if you wish), that you receive source code or can get it if you
want it, that you can change the software or use pieces of it in new
free programs, and that you know you can do these things.
To protect your rights, we need to prevent others from denying you
these rights or asking you to surrender the rights. Therefore, you have
certain responsibilities if you distribute copies of the software, or if
you modify it: responsibilities to respect the freedom of others.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must pass on to the recipients the same
freedoms that you received. You must make sure that they, too, receive
or can get the source code. And you must show them these terms so they
know their rights.
Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) offer you this License
giving you legal permission to copy, distribute and/or modify it.
For the developers' and authors' protection, the GPL clearly explains
that there is no warranty for this free software. For both users' and
authors' sake, the GPL requires that modified versions be marked as
changed, so that their problems will not be attributed erroneously to
authors of previous versions.
Some devices are designed to deny users access to install or run
modified versions of the software inside them, although the manufacturer
can do so. This is fundamentally incompatible with the aim of
protecting users' freedom to change the software. The systematic
pattern of such abuse occurs in the area of products for individuals to
use, which is precisely where it is most unacceptable. Therefore, we
have designed this version of the GPL to prohibit the practice for those
products. If such problems arise substantially in other domains, we
stand ready to extend this provision to those domains in future versions
of the GPL, as needed to protect the freedom of users.
Finally, every program is threatened constantly by software patents.
States should not allow patents to restrict development and use of
software on general-purpose computers, but in those that do, we wish to
avoid the special danger that patents applied to a free program could
make it effectively proprietary. To prevent this, the GPL assures that
patents cannot be used to render the program non-free.
The precise terms and conditions for copying, distribution and
modification follow.

infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.
To "convey" a work means any kind of propagation that enables other
parties to make or receive copies. Mere interaction with a user through
a computer network, with no transfer of a copy, is not conveying.
An interactive user interface displays "Appropriate Legal Notices"
to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License. If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.
1. Source Code.
The "source code" for a work means the preferred form of the work
for making modifications to it. "Object code" means any non-source
form of a work.
A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.
The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form. A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.
The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities. However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work. For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.
The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.
The Corresponding Source for a work in source code form is that
same work.
2. Basic Permissions.
All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met. This License explicitly affirms your unlimited
permission to run the unmodified Program. The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work. This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not
convey, without conditions so long as your license otherwise remains
in force. You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you
with facilities for running those works, provided that you comply with
the terms of this License in conveying all material for which you do
not control copyright. Those thus making or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of
your copyrighted material outside their relationship with you.
Conveying under any other circumstances is permitted solely under
the conditions stated below. Sublicensing is not allowed; section 10
makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.
When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention
is effected by exercising rights under this License with respect to
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's
users, your or third parties' legal rights to forbid circumvention of
technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and
appropriately publish on each copy an appropriate copyright notice;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.
You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified
it, and giving a relevant date.
b) The work must carry prominent notices stating that it is
released under this License and any conditions added under section
7. This requirement modifies the requirement in section 4 to
"keep intact all notices".
c) You must license the entire work, as a whole, under this
License to anyone who comes into possession of a copy. This
License will therefore apply, along with any applicable section 7
additional terms, to the whole of the work, and all its parts,
regardless of how they are packaged. This License gives no
permission to license the work in any other way, but it does not
invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your
work need not make them do so.
A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit. Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:
a) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium
customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by a
written offer, valid for at least three years and valid for as
long as you offer spare parts or customer support for that product
model, to give anyone who possesses the object code either (1) a
copy of the Corresponding Source for all the software in the
product that is covered by this License, on a durable physical
medium customarily used for software interchange, for a price no
more than your reasonable cost of physically performing this
conveying of source, or (2) access to copy the
Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the
written offer to provide the Corresponding Source. This
alternative is allowed only occasionally and noncommercially, and
only if you received the object code with such an offer, in accord
with subsection 6b.
d) Convey the object code by offering access from a designated
place (gratis or for a charge), and offer equivalent access to the
Corresponding Source in the same way through the same place at no
further charge. You need not require recipients to copy the
Corresponding Source along with the object code. If the place to
copy the object code is a network server, the Corresponding Source
may be on a different server (operated by you or a third party)
that supports equivalent copying facilities, provided you maintain
clear directions next to the object code saying where to find the
Corresponding Source. Regardless of what server hosts the
Corresponding Source, you remain obligated to ensure that it is
available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided
you inform other peers where the object code and Corresponding
Source of the work are being offered to the general public at no
charge under subsection 6d.
A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling. In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage. For a particular
product received by a particular user, "normally used" refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product. A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.
"Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source. The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.
If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information. But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).
The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed. Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.
Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law. If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.
When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it. (Additional permissions may be written to require their own
removal in certain cases when you modify the work.) You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.
Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:
a) Disclaiming warranty or limiting liability differently from the
terms of sections 15 and 16 of this License; or
b) Requiring preservation of specified reasonable legal notices or
author attributions in that material or in the Appropriate Legal
Notices displayed by works containing it; or
c) Prohibiting misrepresentation of the origin of that material, or
requiring that modified versions of such material be marked in
reasonable ways as different from the original version; or
d) Limiting the use for publicity purposes of names of licensors or
authors of the material; or
e) Declining to grant rights under trademark law for use of some
trade names, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that
material by anyone who conveys the material (or modified versions of
it) with contractual assumptions of liability to the recipient, for
any liability that these contractual assumptions directly impose on
those licensors and authors.
All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10. If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term. If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.
If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly
provided under this License. Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).
However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the copyright
holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License. If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive or
run a copy of the Program. Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance. However,
nothing other than this License grants you permission to propagate or
modify any covered work. These actions infringe copyright if you do
not accept this License. Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License. You are not responsible
for enforcing compliance by third parties with this License.
An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations. If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License. For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based. The
work thus licensed is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent claims
owned or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.
Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.
In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement). To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.
If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients. "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.
A patent license is "discriminatory" if it does not include within
the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are
specifically granted under this License. You may not convey a covered
work if you are a party to an arrangement with a third party that is
in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work
conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey it at all. For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey
the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.
13. Use with the GNU Affero General Public License.
Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU Affero General Public License into a single
combined work, and to convey the resulting work. The terms of this
License will continue to apply to the part which is the covered work,
but the special requirements of the GNU Affero General Public License,
section 13, concerning interaction through a network will apply to the
combination as such.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of
the GNU General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the
Program specifies that a certain numbered version of the GNU General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation. If the Program does not specify a version number of the
GNU General Public License, you may choose any version ever published
by the Free Software Foundation.
If the Program specifies that a proxy can decide which future
versions of the GNU General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.
Later license versions may give you additional or different
permissions. However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
state the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software: you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation, either version 3 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program. If not, see <http://www.gnu.org/licenses/>.
Also add information on how to contact you by electronic and paper mail.
If the program does terminal interaction, make it output a short
notice like this when it starts in an interactive mode:
<program> Copyright (C) <year> <name of author>
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, your program's commands
might be different; for a GUI interface, you would use an "about box".
You should also get your employer (if you work as a programmer) or school,
if any, to sign a "copyright disclaimer" for the program, if necessary.
For more information on this, and how to apply and follow the GNU GPL, see
<http://www.gnu.org/licenses/>.
The GNU General Public License does not permit incorporating your program
into proprietary programs. If your program is a subroutine library, you
may consider it more useful to permit linking proprietary applications with
the library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License. But first, please read
<http://www.gnu.org/philosophy/why-not-lgpl.html>.

% @multitable macros
% Amy Hendrickson, 8/18/94, 3/6/96
%
% @multitable ... @end multitable will make as many columns as desired.
% Contents of each column will wrap at width given in preamble. Width
% can be specified either with sample text given in a template line,
% or in percent of \hsize, the current width of text on page.
% Table can continue over pages but will only break between lines.
% To make preamble:
%
% Either define widths of columns in terms of percent of \hsize:
% @multitable @columnfractions .25 .3 .45
% @item ...
%
% Numbers following @columnfractions are the percent of the total
% current hsize to be used for each column. You may use as many
% columns as desired.
% Or use a template:
% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
% @item ...
% using the widest term desired in each column.
% Each new table line starts with @item, each subsequent new column
% starts with @tab. Empty columns may be produced by supplying @tab's
% with nothing between them for as many times as empty columns are needed,
% ie, @tab@tab@tab will produce two empty columns.
% @item, @tab do not need to be on their own lines, but it will not hurt
% if they are.
% Sample multitable:
% @multitable {Column 1 template} {Column 2 template} {Column 3 template}
% @item first col stuff @tab second col stuff @tab third col
% @item
% first col stuff
% @tab
% second col stuff
% @tab
% third col
% @item first col stuff @tab second col stuff
% @tab Many paragraphs of text may be used in any column.
%
% They will wrap at the width determined by the template.
% @item@tab@tab This will be in third column.
% @end multitable
% Default dimensions may be reset by user.
% @multitableparskip is vertical space between paragraphs in table.
% @multitableparindent is paragraph indent in table.
% @multitablecolmargin is horizontal space to be left between columns.
% @multitablelinespace is space to leave between table items, baseline
% to baseline.
% 0pt means it depends on current normal line spacing.

my @conds = $set->conds;
# Return one of the Condition involved in $set.
my $cond = $set->one_cond;
# Return true iff $set is always true (i.e. its subconditions
# cover all cases).
if ($set->true) { ... }
# Return false iff $set is always false (i.e. is empty, or contains
# only false conditions).
if ($set->false) { ... }
# Return a string representing the DisjConditions.
# "COND1_TRUE COND2_FALSE | COND3_FALSE"
my $str = $set->string;
# Return a human readable string representing the DisjConditions.

=head1 DESCRIPTION
A C<DisjConditions> is a disjunction of C<Condition>s. In Automake
they are used to represent the conditions into which Makefile
variables and Makefile rules are defined.
If the variable C<VAR> is defined as
if COND1
if COND2
VAR = value1
endif
endif
if !COND3
if COND4
VAR = value2
endif
endif
then it will be associated a C<DisjConditions> created with
the following statement.
new Automake::DisjConditions
(new Automake::Condition ("COND1_TRUE", "COND2_TRUE"),
new Automake::Condition ("COND3_FALSE", "COND4_TRUE"));
As you can see, a C<DisjConditions> is made from a list of
C<Condition>s. Since C<DisjConditions> is a disjunction, and
C<Condition> is a conjunction, the above can be read as
follows.
(COND1 and COND2) or ((not COND3) and COND4)
That's indeed the condition in which C<VAR> has a value.
Like C<Condition> objects, a C<DisjConditions> object is unique
with respect to its conditions. Two C<DisjConditions> objects created
for the same set of conditions will have the same address. This makes
it easy to compare C<DisjConditions>s: just compare the references.
=head2 Methods
=over 4
=item C<$set = new Automake::DisjConditions [@conds]>
Create a C<DisjConditions> object from the list of C<Condition>
objects passed in arguments.
If the C<@conds> list is empty, the C<DisjConditions> is assumed to be
false.
As explained previously, the reference (object) returned is unique
with respect to C<@conds>. For this purpose, duplicate elements are
ignored.

=head1 DESCRIPTION
This class gathers data related to one Makefile-variable definition.
=head2 Constants
=over 4
=item C<VAR_AUTOMAKE>, C<VAR_CONFIGURE>, C<VAR_MAKEFILE>
Possible owners for variables. A variable can be defined
by Automake, in F<configure.ac> (using C<AC_SUBST>), or in
the user's F<Makefile.am>.
=cut
# Defined so that the owner of a variable can only be increased (e.g
# Automake should not override a configure or Makefile variable).
use constant VAR_AUTOMAKE => 0; # Variable defined by Automake.
use constant VAR_CONFIGURE => 1;# Variable defined in configure.ac.
use constant VAR_MAKEFILE => 2; # Variable defined in Makefile.am.
=item C<VAR_ASIS>, C<VAR_PRETTY>, C<VAR_SILENT>, C<VAR_SORTED>
Possible print styles. C<VAR_ASIS> variables should be output as-is.
C<VAR_PRETTY> variables are wrapped on multiple lines if they cannot
fit on one. C<VAR_SILENT> variables are not output at all. Finally,
C<VAR_SORTED> variables should be sorted and then handled as
C<VAR_PRETTY> variables.
C<VAR_SILENT> variables can also be overridden silently (unlike the
other kinds of variables whose overriding may sometimes produce
warnings).
=cut
# Possible values for pretty.
use constant VAR_ASIS => 0; # Output as-is.
use constant VAR_PRETTY => 1; # Pretty printed on output.
use constant VAR_SILENT => 2; # Not output. (Can also be
# overridden silently.)
use constant VAR_SORTED => 3; # Sorted and pretty-printed.
=back
=head2 Methods
C<VarDef> defines the following methods in addition to those inherited
from L<Automake::ItemDef>.
=over 4
=item C<my $def = new Automake::VarDef ($varname, $value, $comment, $location, $type, $owner, $pretty)>
Create a new Makefile-variable definition. C<$varname> is the name of
the variable being defined and C<$value> its value.
C<$comment> is any comment preceding the definition. (Because
Automake reorders variable definitions in the output, it also tries to
carry comments around.)
C<$location> is the place where the definition occurred, it should be
an instance of L<Automake::Location>.
C<$type> should be C<''> for definitions made with C<=>, and C<':'>
for those made with C<:=>.
C<$owner> specifies who owns the variables, it can be one of
C<VAR_AUTOMAKE>, C<VAR_CONFIGURE>, or C<VAR_MAKEFILE> (see these
definitions).
Finally, C<$pretty> tells how the variable should be output, and can
be one of C<VAR_ASIS>, C<VAR_PRETTY>, or C<VAR_SILENT>, or
C<VAR_SORTED> (see these definitions).

indicating where the change took place.

=head1 NAME
Automake::Rule - support for rules definitions
=head1 SYNOPSIS
use Automake::Rule;
use Automake::RuleDef;
=head1 DESCRIPTION
This package provides support for Makefile rule definitions.
An C<Automake::Rule> is a rule name associated to possibly
many conditional definitions. These definitions are instances
of C<Automake::RuleDef>.
Therefore obtaining the value of a rule under a given
condition involves two lookups. One to look up the rule,
and one to look up the conditional definition:
my $rule = rule $name;
if ($rule)
{
my $def = $rule->def ($cond);
if ($def)
{
return $def->location;
}
...
}
...
when it is known that the rule and the definition
being looked up exist, the above can be simplified to
return rule ($name)->def ($cond)->location; # do not write this.
but is better written
return rrule ($name)->rdef ($cond)->location;
or even
return rruledef ($name, $cond)->location;
The I<r> variants of the C<rule>, C<def>, and C<ruledef> methods add
an extra test to ensure that the lookup succeeded, and will diagnose
failures as internal errors (with a message which is much more
informative than Perl's warning about calling a method on a
non-object).

=item C<%dependencies>
Holds the dependencies of targets which dependencies are factored.
Typically, C<.PHONY> will appear in plenty of F<*.am> files, but must
be output once. Arguably all pure dependencies could be subject to
this factoring, but it is not unpleasant to have paragraphs in
Makefile: keeping related stuff altogether.

Pattern that matches all know input extensions (i.e. extensions used
by the languages supported by Automake). Using this pattern (instead
of '\..*$') to match extensions allows Automake to support dot-less

New extensions should be registered with C<accept_extensions>.

directory (which includes the case of absolute file names), and then,
if the file name is not absolute, look in C<@include>.
If the file is flagged as optional (ends with C<?>), then return undef
if absent, otherwise exit with error.

'foO'> answer the same thing. Hence if a package distributes its own
F<CHANGELOG> file, but has no F<ChangeLog> file, automake would still
try to distribute F<ChangeLog> (because it thinks it exists) in
addition to F<CHANGELOG>, although it is impossible for these two
files to be in the same directory (the two file names designate the
same file).

=head1 DESCRIPTION
This packages manages Automake's options and strictness settings.
Options can be either local or global. Local options are set using an
C<AUTOMAKE_OPTIONS> variable in a F<Makefile.am> and apply only to
this F<Makefile.am>. Global options are set from the command line or
passed as an argument to C<AM_INIT_AUTOMAKE>, they apply to all
F<Makefile.am>s.

# Values are the Automake::Location of the definition.

# Whether process_option_list has already been called for the current
# Makefile.am.

# Whether process_global_option_list has already been called.
use vars '$_global_options_processed';

In other words, this gets rid of all local options in use by the
previous F<Makefile.am>.

=item C<$value = option ($name)>

Query the state of an option. If the option is unset, this
returns the empty list. Otherwise it returns the option's value,
as set by C<set_option> or C<set_global_option>.
Note that C<global_option> should be used only when it is
important to make sure an option hasn't been set locally.
Otherwise C<option> should be the standard function to
check for options (be they global or local).

Process Automake's option lists. C<@list> should be a list of hash
references with keys C<option> and C<where>, where C<option> is an
option as they occur in C<AUTOMAKE_OPTIONS> or C<AM_INIT_AUTOMAKE>,
and C<where> is the location where that option occurred.
These functions should be called at most once for each set of options
having the same precedence; i.e., do not call it twice for two options
from C<AM_INIT_AUTOMAKE>.
Return 0 on error, 1 otherwise.

=head1 DESCRIPTION
C<Automake::XFile> inherits from C<IO::File>. It provides the method
C<name> returning the file name. It provides dying versions of the
methods C<close>, C<lock> (corresponding to C<flock>), C<new>,
C<open>, C<seek>, and C<truncate>. It also overrides the C<getline>
and C<getlines> methods to translate C<\r\n> to C<\n>.

This packages defines channels that can be used in Automake to
output diagnostics and other messages (via C<msg()>). It also defines
some helper function to enable or disable these channels, and some
shorthand function to output on specific channels.

Automake::Variable - support for variable definitions
=head1 SYNOPSIS
use Automake::Variable;
use Automake::VarDef;
# Defining a variable.
Automake::Variable::define($varname, $owner, $type,
$cond, $value, $comment,
$where, $pretty)
# Looking up a variable.
my $var = var $varname;
if ($var)
{
...
}
# Looking up a variable that is assumed to exist.
my $var = rvar $varname;
# The list of conditions where $var has been defined.
# ($var->conditions is an Automake::DisjConditions,
# $var->conditions->conds is a list of Automake::Condition.)
my @conds = $var->conditions->conds
# Access to the definition in Condition $cond.
# $def is an Automake::VarDef.
my $def = $var->def ($cond);
if ($def)
{
...
}
# When the conditional definition is assumed to exist, use
my $def = $var->rdef ($cond);
=head1 DESCRIPTION
This package provides support for Makefile variable definitions.
An C<Automake::Variable> is a variable name associated to possibly
many conditional definitions. These definitions are instances
of C<Automake::VarDef>.
Therefore obtaining the value of a variable under a given
condition involves two lookups. One to look up the variable,
and one to look up the conditional definition:
my $var = var $name;
if ($var)
{
my $def = $var->def ($cond);
if ($def)
{
return $def->value;
}
...
}
...
When it is known that the variable and the definition
being looked up exist, the above can be simplified to
return var ($name)->def ($cond)->value; # Do not write this.
but is better written
return rvar ($name)->rdef ($cond)->value;
or even
return rvardef ($name, $cond)->value;
The I<r> variants of the C<var>, C<def>, and C<vardef> methods add an
extra test to ensure that the lookup succeeded, and will diagnose
failures as internal errors (with a message which is much more
informative than Perl's warning about calling a method on a
non-object).

Get the value of C<$var> as a list, given a specified condition,

C<$cond> is the condition of interest. C<$var> does not need
to be defined for condition C<$cond> exactly, but it needs
to be defined for at most one condition implied by C<$cond>.
C<$parent> and C<$parent_cond> designate the name and the condition
of the parent variable, i.e., the variable in which C<$var> is
being expanded. These are used in diagnostics.
For example, if C<A> is defined as "C<foo $(B) bar>" in condition
C<TRUE>, calling C<rvar ('A')->value_as_list (TRUE)> will return
C<("foo", "$(B)", "bar")>.

Return the contents of C<$var> as a list, split on whitespace. This

preserves C<@...@> substitutions.
C<%options> is a list of option for C<Variable::traverse_recursively>
(see this method). The most useful is C<cond_filter>:
$var->value_as_list_recursive (cond_filter => $cond)
will return the contents of C<$var> and any subvariable in all
conditions implied by C<$cond>.
C<%options> can also carry options specific to C<value_as_list_recursive>.

C<value_as_list_recursive> to return a list of C<[$location, @values]> pairs.

Split the value of the Automake::Variable C<$var> on space, and
traverse its components recursively.
If C<$cond_filter> is an C<Automake::Condition>, process any
conditions which are true when C<$cond_filter> is true. Otherwise,
process all conditions.
We distinguish two kinds of items in the content of C<$var>.
Terms that look like C<$(foo)> or C<${foo}> are subvariables
and cause recursion. Other terms are assumed to be filenames.
Each time a filename is encountered, C<&fun_item> is called with the
following arguments:
($var, -- the Automake::Variable we are currently
traversing
$val, -- the item (i.e., filename) to process
$cond, -- the Condition for the $var definition we are
examining (ignoring the recursion context)
$full_cond) -- the full Condition, taking into account
conditions inherited from parent variables
during recursion
If C<inner_expand> is set, variable references occurring in filename
(as in C<$(BASE).ext>) are expanded before the filename is passed to
C<&fun_item>.
If C<skip_ac_subst> is set, Autoconf @substitutions@ will be skipped,
i.e., C<&fun_item> will never be called for them.
C<&fun_item> may return a list of items, they will be passed to
C<&fun_store> later on. Define C<&fun_item> or @<&fun_store> as
C<undef> when they serve no purpose.
Once all items of a variable have been processed, the result (of the
calls to C<&fun_items>, or of recursive traversals of subvariables)
are passed to C<&fun_collect>. C<&fun_collect> receives three
arguments:
($var, -- the variable being traversed
$parent_cond, -- the Condition inherited from parent
variables during recursion
@condlist) -- a list of [$cond, @results] pairs
where each $cond appear only once, and @result
are all the results for this condition.
Typically you should do C<$cond->merge ($parent_cond)> to recompute
the C<$full_cond> associated to C<@result>. C<&fun_collect> may
return a list of items, that will be used as the result of
C<Automake::Variable::traverse_recursively> (the top-level, or its
recursive calls).

Automake::Location - a class for location tracking, with a stack of contexts
=head1 SYNOPSIS
use Automake::Location;
# Create a new Location object
my $where = new Automake::Location "foo.c:13";
# Change the location
$where->set ("foo.c:14");
# Get the location (without context).
# Here this should print "foo.c:14"
print $where->get, "\n";
# Push a context, and change the location
$where->push_context ("included from here");
$where->set ("bar.h:1");
# Print the location and the stack of context (for debugging)
print $where->dump;
# This should display
# bar.h:1:
# foo.c:14: included from here
# Get the contexts (list of [$location_string, $description])
for my $pair (reverse $where->contexts)
{
my ($loc, $descr) = @{$pair};
...
}
# Pop a context, and reset the location to the previous context.
$where->pop_context;
# Clone a Location. Use this when storing the state of a location
# that would otherwise be modified.
my $where_copy = $where->clone;
# Serialize a Location object (for passing through a thread queue,
# for example)
my @array = $where->serialize ();
# De-serialize: recreate a Location object from a queue.
my $where = new Automake::Location::deserialize ($queue);
=head1 DESCRIPTION
C<Location> objects are used to keep track of locations in Automake,
and used to produce diagnostics.
A C<Location> object is made of two parts: a location string, and
a stack of contexts.
For instance if C<VAR> is defined at line 1 in F<bar.h> which was
included at line 14 in F<foo.c>, then the location string should be
C<"bar.h:10"> and the context should be the pair (C<"foo.c:14">,
C<"included from here">).
Section I<SYNOPSIS> shows how to setup such a C<Location>, and access
the location string or the stack of contexts.
You can pass a C<Location> to C<Automake::Channels::msg>.

Automake::Wrap - a paragraph formatter
=head1 SYNOPSIS
use Automake::Wrap 'wrap', 'makefile_wrap';
print wrap ($first_ident, $next_ident, $end_of_line, $max_length,
@values);
print makefile_wrap ("VARIABLE = ", " ", @values);
=head1 DESCRIPTION
This modules provide facility to format list of strings. It is
comparable to Perl's L<Text::Wrap>, however we can't use L<Text::Wrap>
because some versions will abort when some word to print exceeds the
maximum length allowed. (Ticket #17141, fixed in Perl 5.8.0.)

Format C<@values> as a block of text that starts with C<$head>,
followed by the strings in C<@values> separated by spaces or by
C<"$eol\n$fill"> so that the length of each line never exceeds
C<$max_len>.
The C<$max_len> constraint is ignored for C<@values> items which
are too big to fit alone one a line.
The constructed paragraph is C<"\n">-terminated.

A space is appended to C<$head> when this is not already
the case.
This can be used to format variable definitions or dependency lines.

Automake::Channels - support functions for error and warning management
=head1 SYNOPSIS

# Register a channel to output warnings about unused variables.

# Register a channel for system errors.

=head1 DESCRIPTION
This perl module provides support functions for handling diagnostic
channels in programs. Channels can be registered to convey fatal,
error, warning, or debug messages. Each channel has various options
(e.g. is the channel silent, should duplicate messages be removed,
etc.) that can also be overridden on a per-message basis.

=over 4
=item C<UP_NONE>, C<UP_TEXT>, C<UP_LOC_TEXT>
Possible values for the C<uniq_part> options. This selects the part
of the message that should be considered when filtering out duplicates.
If C<UP_LOC_TEXT> is used, the location and the explanation message
are used for filtering. If C<UP_TEXT> is used, only the explanation
message is used (so the same message will be filtered out if it appears
at different locations). C<UP_NONE> means that duplicate messages
should be output.

=item C<US_LOCAL>, C<US_GLOBAL>
Possible values for the C<uniq_scope> options.
Use C<US_GLOBAL> for error messages that should be printed only
once during the execution of the program, C<US_LOCAL> for message that
should be printed only once per file. (Actually, C<Channels> does not
do this now when files are changed, it relies on you calling
C<reset_local_duplicates> when this happens.)

=head2 Options
Channels accept the options described below. These options can be
passed as a hash to the C<register_channel>, C<setup_channel>, and C<msg>
functions. The possible keys, with their default value are:
=over
=item C<type =E<gt> 'warning'>
The type of the channel. One of C<'debug'>, C<'warning'>, C<'error'>, or
C<'fatal'>. Fatal messages abort the program when they are output.
Error messages update the exit status. Debug and warning messages are
harmless, except that warnings are treated as errors if
C<$warnings_are_errors> is set.
=item C<exit_code =E<gt> 1>
The value to update C<$exit_code> with when a fatal or error message
is emitted. C<$exit_code> is also updated for warnings output
when C<$warnings_are_errors> is set.
=item C<file =E<gt> \*STDERR>
The file where the error should be output.
=item C<silent =E<gt> 0>
Whether the channel should be silent. Use this do disable a
category of warning, for instance.
=item C<ordered =E<gt> 1>
Whether, with multi-threaded execution, the message should be queued
for ordered output.
=item C<uniq_part =E<gt> UP_LOC_TEXT>
The part of the message subject to duplicate filtering. See the
documentation for the C<UP_NONE>, C<UP_TEXT>, and C<UP_LOC_TEXT>
constants above.
C<uniq_part> can also be set to an arbitrary string that will be used
instead of the message when considering duplicates.
=item C<uniq_scope =E<gt> US_LOCAL>
The scope of duplicate filtering. See the documentation for the
C<US_LOCAL>, and C<US_GLOBAL> constants above.
=item C<header =E<gt> ''>
A string to prepend to each message emitted through this channel.
With partial messages, only the first part will have C<header>
prepended.
=item C<footer =E<gt> ''>
A string to append to each message emitted through this channel.
With partial messages, only the final part will have C<footer>
appended.
=item C<backtrace =E<gt> 0>
Die with a stack backtrace after displaying the message.
=item C<partial =E<gt> 0>
When set, indicates a partial message that should
be output along with the next message with C<partial> unset.
Several partial messages can be stacked this way.
Duplicate filtering will apply to the I<global> message resulting from
all I<partial> messages, using the options from the last (non-partial)
message. Linking associated messages is the main reason to use this
option.
For instance the following messages
msg 'channel', 'foo:2', 'redefinition of A ...';
msg 'channel', 'foo:1', '... A previously defined here';
msg 'channel', 'foo:3', 'redefinition of A ...';
msg 'channel', 'foo:1', '... A previously defined here';
will result in
foo:2: redefinition of A ...
foo:1: ... A previously defined here
foo:3: redefinition of A ...
where the duplicate "I<... A previously defined here>" has been
filtered out.
Linking these messages using C<partial> as follows will prevent the
fourth message to disappear.
msg 'channel', 'foo:2', 'redefinition of A ...', partial => 1;
msg 'channel', 'foo:1', '... A previously defined here';
msg 'channel', 'foo:3', 'redefinition of A ...', partial => 1;
msg 'channel', 'foo:1', '... A previously defined here';
Note that because the stack of C<partial> messages is printed with the
first non-C<partial> message, most options of C<partial> messages will
be ignored.

=item C<msg ($channel, $location, $message, [%options])>
Emit a message on C<$channel>, overriding some options of the channel with
those specified in C<%options>. Obviously C<$channel> must have been
registered with C<register_channel>.
C<$message> is the text of the message, and C<$location> is a location
associated to the message.
For instance to complain about some unused variable C<mumble>
declared at line 10 in F<foo.c>, one could do:
msg 'unused', 'foo.c:10', "unused variable 'mumble'";
If channel C<unused> is not silent (and if this message is not a duplicate),
the following would be output:
foo.c:10: unused variable 'mumble'
C<$location> can also be an instance of C<Automake::Location>. In this
case, the stack of contexts will be displayed in addition.
If C<$message> contains newline characters, C<$location> is prepended
to each line. For instance,
msg 'error', 'somewhere', "1st line\n2nd line";
becomes
somewhere: 1st line
somewhere: 2nd line
If C<$location> is an empty string, it is replaced by the name of the
program. Actually, if you don't use C<%options>, you can even
elide the empty C<$location>. Thus
msg 'fatal', '', 'fatal error';
msg 'fatal', 'fatal error';
both print
progname: fatal error

=item C<dup_channel_setup ()>, C<drop_channel_setup ()>
Sometimes it is necessary to make temporary modifications to channels.
For instance one may want to disable a warning while processing a
particular file, and then restore the initial setup. These two
functions make it easy: C<dup_channel_setup ()> saves a copy of the
current configuration for later restoration by
C<drop_channel_setup ()>.
You can think of this as a stack of configurations whose first entry
is the active one. C<dup_channel_setup ()> duplicates the first
entry, while C<drop_channel_setup ()> just deletes it.

=item C<buffer_messages (@types)>, C<flush_messages ()>
By default, when C<msg> is called, messages are processed immediately.
Sometimes it is necessary to delay the output of messages.
For instance you might want to make diagnostics before
channels have been completely configured.
After C<buffer_messages(@types)> has been called, messages sent with
C<msg> to a channel whose type is listed in C<@types> will be stored in a
list for later processing.
This backlog of messages is processed when C<flush_messages> is
called, with the current channel options (not the options in effect,
at the time of C<msg>). So for instance, if some channel was silenced
in the meantime, messages to this channel will not be printed.
C<flush_messages> cancels the effect of C<buffer_messages>. Following
calls to C<msg> are processed immediately as usual.

=head1 DESCRIPTION
A C<Condition> is a conjunction of conditionals (i.e., atomic conditions
defined in F<configure.ac> by C<AM_CONDITIONAL>. In Automake they
are used to represent the conditions into which F<Makefile> variables and
F<Makefile> rules are defined.
If the variable C<VAR> is defined as
if COND1
if COND2
VAR = value
endif
endif
then it will be associated a C<Condition> created with
the following statement.
new Automake::Condition "COND1_TRUE", "COND2_TRUE";
Remember that a C<Condition> is a I<conjunction> of conditionals, so
the above C<Condition> means C<VAR> is defined when C<COND1>
B<and> C<COND2> are true. There is no way to express disjunctions
(i.e., I<or>s) with this class (but see L<DisjConditions>).
Another point worth to mention is that each C<Condition> object is
unique with respect to its conditionals. Two C<Condition> objects
created for the same set of conditionals will have the same address.
This makes it easy to compare C<Condition>s: just compare the
references.
my $c1 = new Automake::Condition "COND1_TRUE", "COND2_TRUE";
my $c2 = new Automake::Condition "COND1_TRUE", "COND2_TRUE";
$c1 == $c2; # True!
=head2 Methods
=over 4
=item C<$cond = new Automake::Condition [@conds]>
Return a C<Condition> objects for the conjunctions of conditionals
listed in C<@conds> as strings.
An item in C<@conds> should be either C<"FALSE">, C<"TRUE">, or have
the form C<"NAME_FALSE"> or C<"NAME_TRUE"> where C<NAME> can be
anything (in practice C<NAME> should be the name of a conditional
declared in F<configure.ac> with C<AM_CONDITIONAL>, but it's not
C<Automake::Condition>'s responsibility to ensure this).
An empty C<@conds> means C<"TRUE">.
As explained previously, the reference (object) returned is unique
with respect to C<@conds>. For this purpose, duplicate elements are
ignored, and C<@conds> is rewritten as C<("FALSE")> if it contains
C<"FALSE"> or two contradictory conditionals (such as C<"NAME_FALSE">
and C<"NAME_TRUE">.)
Therefore the following two statements create the same object (they
both create the C<"FALSE"> condition).
my $c3 = new Automake::Condition "COND1_TRUE", "COND1_FALSE";
my $c4 = new Automake::Condition "COND2_TRUE", "FALSE";
$c3 == $c4; # True!
$c3 == FALSE; # True!

Automake::Version - version comparison
=head1 SYNOPSIS
use Automake::Version;
print "Version $version is older than required version $required\n"
if Automake::Version::check ($version, $required);
=head1 DESCRIPTION
This module provides support for comparing versions string
as they are used in Automake.
A version is a string that looks like
C<MAJOR.MINOR[.MICRO][ALPHA][-FORK]> where C<MAJOR>, C<MINOR>, and
C<MICRO> are digits, C<ALPHA> is a character, and C<FORK> any
alphanumeric word.
Usually, C<ALPHA> is used to label alpha releases or intermediate
snapshots, C<FORK> is used for git branches or patched releases, and
C<MICRO> is used for bug fixes releases on the C<MAJOR.MINOR> branch.
For the purpose of ordering, C<1.4> is the same as C<1.4.0>, but
C<1.4g> is the same as C<1.4.99g>. The C<FORK> identifier is ignored
in the ordering, except when it looks like C<-pMINOR[ALPHA]>: some
versions were labeled like C<1.4-p3a>, this is the same as an alpha
release labeled C<1.4.3a>. Yes, it's horrible, but Automake did not
support two-dot versions in the past.
=head2 FUNCTIONS

=item C<split ($version)>
Split the string C<$version> into the corresponding C<(MAJOR, MINOR,

## Note that this doesn't just cater to obsosete pre-3.x GCC compilers.

## (see the conditional assignment to $gccflag above).
## There are various ways to get dependency output from gcc. Here's
## why we pick this rather obscure method:
## - Don't want to use -MD because we'd like the dependencies to end
## up in a subdir. Having to rename by hand is ugly.
## (We might end up doing this anyway to support other compilers.)
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
## -MM, not -M (despite what the docs say). Also, it might not be
## supported by the other compilers which use the 'gcc' depmode.
## - Using -M directly means running the compiler twice (even worse
## than renaming).

## This next piece of magic avoids the "deleted header file" problem.
## The problem is that when a header file which appears in a .P file
## is deleted, the dependency causes make to die (because there is
## typically no way to rebuild the header). We avoid this by adding
## dummy dependencies for each header file. Too bad gcc doesn't do
## this for us directly.
## Some versions of gcc put a space before the ':'. On the theory
## that the space means something, we add a space to the output as
## well. hp depmode also adds that space, but also prefixes the VPATH
## to the object. Take care to not repeat it in the output.
## Some versions of the HPUX 10.20 sed can't process this invocation
## correctly. Breaking it into two sed invocations is a workaround.

# or in some cases, the newer four-part form:
# CPU_TYPE-MANUFACTURER-KERNEL-OPERATING_SYSTEM

Usage: py-compile [--help] [--version] [--basedir DIR] [--destdir DIR] FILES..."
Byte compile some python scripts FILES. Use --destdir to specify any
leading directory path to the FILES that you don't want to include in the
byte compiled file. Specify --basedir for any additional path information you
do want to be shown in the byte compiled file.
Example:
py-compile --destdir /tmp/pkg-root --basedir /usr/share/test test.py test2.py
