       git-pbuilder - Wrapper around cowbuilder/qemubuilder for git-buildpackage


       DIST=distribution ARCH=architecture [BUILDER=(pbuilder|qemubuilder)] \
           git-pbuilder debbuild-options

       DIST=distribution ARCH=architecture [BUILDER=(pbuilder|qemubuilder)] \
           git-pbuilder (update | create | login) cowbuilder-options


       git-pbuilder is a wrapper around pdebuild intended for use by git-buildpackage.  It
       configures pdebuild to use cowbuilder by default, passes appropriate options to debbuild,
       and sets the base path for cowbuilder based on the environment variable DIST and, if set,
       the environment variable ARCH.  qemubuilder can be selected instead by setting the
       environment variable BUILDER to "qemubuilder", and pbuilder can be selected by setting
       BUILDER to "pbuilder".

       By default, git-pbuilder assumes the target distribution is "sid", the same architecture
       as the cowbuilder default, and uses /var/cache/pbuilder/base-sid.cow if it exists.  If it
       doesn't, /var/cache/pbuilder/base.cow is tried.  If DIST is set, its value is the target
       distribution and /var/cache/pbuilder/base-dist.cow is used instead.  If DIST is "etch" or
       "ebo", --debian-etch-workaround is also passed to cowbuilder.  If ARCH is set, its value
       is the target architecture and /var/cache/pbuilder/base-dist-arch.cow is used, with dist
       being set to "sid" if DIST was not set.

       If qemubuilder is used as the builder, no base directory is used.  Instead, qemubuilder is
       invoked with the --config option pointing to the file

       If pbuilder is used as the builder, git-pbuilder instead looks for
       /var/cache/pbuilder/base-sid.tgz by default and /var/cache/pbuilder/base.tgz if it doesn't
       exist.  If DIST or ARCH are set, they are used to form the expected name of the tgz file
       in the same way as they're used to form the expected base directory for cowbuilder.
       Similar to cowbuilder, --debian-etch-workaround is passed to pbuilder if from the DIST
       setting it looks like the target distribution is etch.

       If git-pbuilder is invoked via a name that starts with "git-*-", the part between the
       hyphens is taken to be the default name of the builder to use.  However, "pbuilder" is
       mapped to cowbuilder for backward compatibility; if you want to use pbuilder, you have to
       explicitly set BUILDER.  The part after the last hyphen is taken to be the default
       distribution (if it contains no additional hyphen) or the default distribution followed by
       the default architecture (if it contains a hyphen).  One can therefore create symlinks
       like "git-pbuilder-squeeze" pointing to git-pbuilder and use that name when wanting to use
       a distribution of "squeeze", or "git-qemubuilder-sid-armel" to use qemubuilder to build
       for the "armel" architecture and the "sid" distribution.  Explicit settings of BUILDER,
       DIST, or ARCH always override any guesses from the command name.

       Any arguments are passed as-is to dpkg-buildpackage via the --debbuildopts option to
       pdebuild.  To pass arguments to the builder instead, put them in the environment variable

       To disable all attempts to discover the base path, tarball, or configuration file and set
       up the pbuilder options and instead rely on the settings in .pbuilderrc, set

       Normally, one does not run this script directly.  Instead, it's used as the builder script
       for git-buildpackage.  To configure git-buildpackage to use it, add a stanza like:

           builder = /path/to/git-pbuilder

       in your gbp.conf file (which can be .gbp.conf in your home directory or at the top level
       of the repository, or gbp.conf in the .git directory).  DIST and ARCH are read as an
       environment variable so that you can set it before running git-buildpackage without having
       to worry about passing parameters through git-buildpackage.

       Alternately, git-pbuilder may be called with an argument of "update", "create", or
       "login".  In this case, it calls cowbuilder (or the configured builder as described above)
       using sudo and passes the corresponding command to the builder, using the same logic as
       above to determine the base directory and distribution.  If the distribution (set in DIST)
       ends in "-backports", one of the following will be added as an --othermirror parameter to
       the builder:

           deb $DIST main
           deb $DIST main

       The first will be used for most distributions, and the second for "squeeze-backports" or

       Any additional arguments to git-pbuilder are passed along to the builder.  Due to how sudo
       works, invoking the builder with an action will not read the user's .pbuilderrc by
       default, so in this case git-pbuilder will add an explicit --configfile option pointing to
       the user's .pbuilderrc if it exists.


           Sets the target architecture.  For a cowbuilder builder, this sets both the base path
           and is passed as the --architecture option.  With qemubuilder, this controls the path
           to the configuration file.  With pbuilder, this sets the tgz path and is passed as

           Sets the builder to use.  The only supported settings are "cowbuilder" (the default),
           "qemubuilder", and "pbuilder".

           Set this environment variable to change the default location for the cowbuilder base
           directories (/var/cache/pbuilder).

           Sets the target distribution.  This is used primarily to determine the base path for
           cowbuilder or pbuilder or the configuration file path for qemubuilder, but it's also
           used to determine whether to pass --debian-etch-workaround to cowbuilder or pbuilder.

           If set to "no", disable the logic that constructs the base path, tarball, or
           configuration file and all other logic to determine the options to pass to the
           builder.  Instead, just run the configured builder and assume its configuration is
           handled elsewhere (such as in .pbuilderrc).  This also suppresses setting
           --buildresult, so the user will need to ensure that the configuration still puts
           packages where git-buildpackage expects them.

           Add additional options for the builder.  These options are passed as-is to cowbuilder,
           qemubuilder, or pbuilder via pdebuild.  The contents of this variable will undergo
           shell expansion, so any arguments containing shell metacharacters or whitespace need
           to be quoted in the value of the environment variable.

           Where to put the result of the build.  The default is ".." (the parent directory).
           This setting is ignored if GIT_PBUILDER_AUTOCONF is set to "no".

           Set this environment variable to change the defualt location for the pbuilder tgz
           files (/var/cache/pbuilder) when BUILDER is set to "pbuilder".


           The default "cowbuilder --basepath" directories, searched for in that order, if
           neither DIST nor ARCH is set.

           The "cowbuilder --basepath" directory used if ARCH is set and DIST is not set.

           The "cowbuilder --basepath" directory used if DIST is set and ARCH is not.

           The "cowbuilder --basepath" directory used if DIST and ARCH are both set.

           and ARCH if BUILDER is set to "pbuilder".

           The "qemubuilder --config" file used.  $ARCH defaults to "armel" and $DIST defaults to
