NAME

       git-debcherry - export commits touching upstream source as patches

SYNOPSIS

       git-debcherry [options] upstream [integration]

DESCRIPTION

       This  program  will  analyze  git  history  and try to create a set of patches meeting the
       following conditions:

           1. Is guaranteed to apply to upstream

           2. Produces the same work tree as integration, outside ./debian

           3. Does not touch ./debian

           4. As much as possible, matches the git history from upstream to integration

BRANCH PARAMETERS

       upstream

              This ref should be suitable for export as a .orig.tar.gz.  In particular note  that
              quilt has no way of deleting files that does not include the material to be deleted
              in the patch, so your upstream branch should include any necessary file deletions.

       integration

              This branch contains all debian packaging, plus any changes introduced to  upstream
              source  by  the debian packager.  This argument is optional.  If integration is not
              passed git-debcherry will use HEAD.

OPTIONS

       The following options are available:

       -o, --output-directory directory

              Place output (patches and  series  file)  in  directory.   If  unspecified,  output
              patches (in mbox format) to stdout.

       -s, --stat

              Only output diffstat of patches

       -d, --debug
              Output  some  debugging  information.  Probably  only useful to developers or those
              reporting bugs.

EXAMPLE

       To export the patches between tag v3.0+dfsg1 and the current branch into ./debian/patches:

        $ git-debcherry -o debian/patches v3.0+dfsg1

NOTES

   PERFORMANCE
       git-debcherry  currently  uses  git-filter-branch(1)  to  rewrite  all  commits   on   the
       integration branch not present upstream. Depending on the number of such commits, this can
       be noticeably slow.

   DELETED FILES
       git-debcherry currently follows dpkg-source(1) in ignoring file deletions.  This  has  the
       positive side effect of not bloating the patches, but if you really need the files deleted
       for the build and/or licensing reasons, you should delete them in upstream.
