.SH NAME
\*(PB \- \*(DS package build description file

.SH DESCRIPTION
This manual page is meant to describe general rules about \fB\*(PB\fPs. Once
a \fB\*(PB\fP is written, the actual package is built using \fBmakepkg\fP and 
installed with \fBpacman\fP.

\fBNOTE:\fP If you have a local copy of the Arch Build System (ABS) tree
on your computer, you can copy the \*(PB.proto file to your new package
build directory and edit it from there.  To acquire/sync the ABS tree, use
the \fBabs\fP script included with \fBpacman\fP.

.SH OPTIONS AND DIRECTIVES
.TP
.B pkgname
The name of the package. This has be a unix-friendly name as it will be
used in the package filename.

.TP
.B pkgver
The version of the software as released from the author (e.g. 2.7.1).

.TP
.B pkgrel
This is the release number specific to the \*(DSs release. This allows package
maintainers to make updates to the package's configure flags, for example.

.TP
.B pkgdesc
This should be a brief description of the package and its functionality. Try to
keep the description to one line of text.

.TP
.B url
This field contains a URL that is associated with the software being packaged.
This is typically the project's website.

.TP
.B license (array)
This field specifies the license(s) that apply to the package. Commonly-used
licenses are found in \fI/usr/share/licenses/common\fP. If you see the
package's license there, simply reference it in the license field (e.g.
\fBlicense=("GPL")\fP). If the package provides a license not found in
\fI/usr/share/licenses/common\fP, then you should include the license in the
package itself and set \fBlicense=("custom")\fP or
\fBlicense=("custom:LicenseName")\fP. The license should be placed in
\fI$startdir/pkg/usr/share/licenses/$pkgname\fP when building the package. If
multiple licenses are applicable for a package, list all of them:
\fBlicenses=('GPL' 'FDL')\fP.

.TP
.B install
Specifies a special install script that is to be included in the package. This
file should reside in the same directory as the \fB\*(PB\fP, and will be copied
into the package by \fBmakepkg\fP. It does not need to be included in the
\fIsource\fP array (e.g. \fBinstall=pkgname.install\fP).

.TP
.B source \fI(array)\fP
An array of source files required to build the package. Source files must
either reside in the same directory as the \fB\*(PB file\fP, or be a
fully-qualified URL that makepkg will use to download the file.  In order to
make the PKGBUILD as useful as possible, use the \fB$pkgname\fP and
\fB$pkgver\fP variables if possible when specifying the download location.

.TP
.B noextract \fI(array)\fP
An array of filenames corresponding to those from the \fBsource\fP array. Files
listed here will not be extracted with the rest of the source files. This is
useful for packages which use compressed data which is downloaded but not
necessary to uncompress.

.TP
.B md5sums \fI(array)\fP
This array contains an MD5 hash for every source file specified in the
\fBsource\fP array (in the same order). \fBmakepkg\fP will use this to verify
source file integrity during subsequent builds. To easily generate md5sums, run
"makepkg -g >> \*(PB".  If desired, move the \fBmd5sums\fP line to an
appropriate location.  NOTE: \fBmakepkg\fP supports multiple integrity
algorithms and their corresponding arrays (i.e. sha1sums for the SHA1
algorithm); however, official packages use only md5sums for the time being.

.TP
.B sha1sums, etc.
Alternative integrity checks that \fBmakepkg\fP supports, as noted in
\fBmd5sums\fP above.

.TP
.B groups \fI(array)\fP
An array of symbolic names that represent groups of packages, allowing
you to install multiple packages by requesting a single target. For example,
one could install all KDE packages by installing the 'kde' group.

.TP
.B arch \fI(array)\fP
Defines on which architectures the given package is available (e.g.
\fBarch=('i686' 'x86_64')\fP). 

.TP
.B backup \fI(array)\fP 
A space-delimited array of filenames, \fIwithout\fP preceding slashes, that
should be backed up if the package is removed or upgraded. This is commonly
used for packages placing configuration files in /etc. See \fBHANDLING CONFIG
FILES\fP in the \fBpacman\fP manpage for more information.

.TP
.B depends \fI(array)\fP 
An array of packages that this package depends on to run. Packages in this list
should be surrounded with single quotes and contain at least the package name.
Entries can also include a version requirement of the form
\fB'name<>version'\fP, where <> is one of three comparisons: \fI>=\fP (greater
than or equal to), \fI<=\fP (less than or equal to), or \fI=\fP (equal to).

.TP
.B makedepends \fI(array)\fP
An array of packages that this package depends on to build, but are not needed
at runtime.  Packages in this list follow the same format as \fBdepends\fP.

.TP
.B conflicts \fI(array)\fP
An array of packages that will conflict with this package (i.e. they cannot
both be installed at the same time). This directive follows the same format as
\fIdepends\fP, except you cannot specify versions.

.TP
.B provides \fI(array)\fP
An array of "virtual provisions" that this package provides. This allows a
package to provide dependencies other than its own package name. For example,
the dcron package can provide 'cron', which allows packages to depend on 'cron'
rather than 'dcron OR fcron'.

.TP
.B replaces \fI(array)\fP
An array of packages that this package should replace, and can be used to
handle renamed/combined packages. For example, if the 'j2re' package is renamed
to 'jre', this directive allows future upgrades to continue as expected even
though the package has moved.

.TP
.B options \fI(array)\fP
This array allows you to override some of \fBmakepkg\fP's default behavior when
building packages. To set an option, just include the option name in the
\fBoptions\fP array. To reverse the default behavior, place an "!" at the front
of the option. Only specify the options you specifically want to override, the
rest will be taken from \fBmakepkg.conf\fP. NOTE: 'force' is a special option
only used in \fB\*(PB\fPs, do not use it unless you know what you are doing.
.RS
.TP
.B strip
Strip symbols from binaries and libraries. If you frequently use a debugger on
programs or libraries, it may be helpful to disable this option.
.TP
.B docs
Save doc and info directories. If you wish to delete doc and info directories,
specify "!docs" in the array.
.TP
.B libtool
Leave libtool (.la) files in packages. Specify "!libtool" to remove them.
.TP
.B emptydirs
Leave empty directories in packages.
.TP
.B ccache
Allow the use of \fBccache\fP during build. More useful in its negative form
"!ccache" with select packages that have problems building with \fBccache\fP.
.TP
.B distcc
Allow the use of \fBdistcc\fP during build. More useful in its negative form
"!distcc" with select packages that have problems building with \fBdistcc\fP.
.TP
.B makeflags
Allow the use of user-specific makeflags during build as specified in
\fBmakepkg.conf\fP. More useful in its negative form "!makeflags" with select
packages that have problems building with custom makeflags such as "-j2" (or
higher).
.TP
.B force
Force the package to be upgraded by a \fBpacman\fP system upgrade operation,
even if the version number would normally not trigger such an upgrade. This is
useful when the version numbering scheme of a package changes (or is
alphanumeric).
.RE

.SH INSTALL/UPGRADE/REMOVE SCRIPTING
\fBPacman\fP has the ability to store and execute a package-specific script
when it installs, removes, or upgrades a package.  This allows a package to
configure itself after installation and do the opposite right before it is
removed.

The exact time the script is run varies with each operation:

.TP
.B pre_install
script is run right before files are extracted.

.TP
.B post_install
script is run right after files are extracted.

.TP
.B pre_upgrade
script is run right before files are extracted.

.TP
.B post_upgrade
script is run after files are extracted.

.TP
.B pre_remove
script is run right before files are removed.

.TP
.B post_remove
script is run right after files are removed.

.P
To use this feature, create a file such as 'pkgname.install' and put it in
the same directory as the \fB\*(PB\fP script.  Then use the \fBinstall\fP
directive:

.RS
.nf
install=pkgname.install
.fi
.RE

The install script does not need to be specified in the \fBsource\fP array.
A template install file is available in the ABS tree (/var/abs/install.proto).

.SH EXAMPLE
The following is an example \fB\*(PB\fP for the 'modutils' package. For more
examples, look through the ABS tree.
