NAME

   origtargz - fetch the orig tarball of a Debian package from various
   sources, and unpack it

SYNOPSIS

   origtargz [OPTIONS] [--unpack[=no|once|yes]]
   origtargz --help

DESCRIPTION

   origtargz downloads the orig tarball of a Debian package, and also
   unpacks it into the current directory, if it just contains a debian
   directory. The main use for origtargz is with debian-dir-only
   repository checkouts, but it is useful as a general tarball download
   wrapper. The version number for the tarball to be downloaded is
   determined from debian/changelog. It should be invoked from the top
   level directory of an unpacked Debian source package.

   Various download locations are tried:

   *   First, an existing file is looked for.

   *   Directories given with --path are searched.

   *   pristine-tar is tried.

   *   apt-get source is tried when apt-cache showsrc reports a matching
       version.

   *   Finally, uscan --download-current-version is tried.

   When asked to unpack the orig tarball, origtargz will remove all files
   and directories from the current directory, except the debian
   directory, and the VCS repository directories. Some files outside
   debian/ which are often stored in VCS even for debian-dir-only
   repositories are also preserved (.bzr-builddeb, .gitignore, .hgignore).
   Note that this will drop all non-committed changes for the patch system
   in use (e.g. source format "3.0 (quilt)"), and will even remove all
   patches from the package when no patch system is in use (the original
   "1.0" source format).

   The default behavior is to unpack the orig tarball if the current
   directory is empty except for a debian directory and the VCS files
   mentioned above.

NOTES

   Despite origtargz being called "targz", it will work with any
   compression scheme used for the tarball.

   A similar tool to unpack orig tarballs is uupdate(1). uupdate creates a
   new working directory, unpacks the tarball, and applies the Debian
   .diff.gz changes. In contrast, origtargz uses the current directory,
   keeping VCS metadata.

   For Debian package repositories that keep the full upstream source,
   other tools should be used to upgrade the repository from the new
   tarball. See gbp-import-orig(1) and svn-upgrade(1) for examples.
   origtargz is still useful for downloading the current tarball.

OPTIONS

   -p, --path directory
       Add directory to the list of locations to search for an existing
       tarball.  When found, a hardlink is created if possible, otherwise
       a symlink.

   -u, --unpack[=no|once|yes]
       Unpack the downloaded orig tarball to the current directory,
       replacing everything except the debian directory. Existing files
       are removed, except for debian/ and VCS files. Preserved are: .bzr,
       .bzrignore, .bzr-builddeb, .git, .gitignore, .hg, .hgignore, _darcs
       and .svn.

       no  Do not unpack the orig tarball.

       once (default when --unpack is not used)
           If the current directory contains only a debian directory (and
           possibly some dotfiles), unpack the orig tarball. This is the
           default behavior.

       yes (default for --unpack without argument)
           Always unpack the orig tarball.

   -d, --download-only
       Alias for --unpack=no.

   -t, --tar-only
       When using apt-get source, pass --tar-only to it. The default is to
       download the full source package including .dsc and .diff.gz or
       .debian.tar.gz components so debdiff can be used to diff the last
       upload to the next one. With --tar-only, only download the
       .orig.tar.* file.

   --clean
       Remove existing files as with --unpack. Note that like --unpack,
       this will remove upstream files even if they are stored in VCS.
