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 optionally unpacks it into
       the current directory. The version number to be used is determined from debian/changelog.
       The main use for origtargz is with debian-dir-only repository checkouts. 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 on the first invocation of origtargz in
       a debian-dir-only checkout.

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 git-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, 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.
