DESCRIPTION

       gbp import-ref merges upstream git commits onto your debian-branch You can either  specify
       a  branch  to merge, give an upstream version or specify the commit id directly. If no tag
       exists for the imported commit it will be automatically created.

OPTIONS

       --version
              Print version of the program, i.e. version of the git-buildpackage suite

       -v, --verbose
              Verbose execution

       -h, --help
              Print help and exit

       --color=[auto|on|off]
              Whether to use colored output.

       --color-scheme=COLOR_SCHEME
              Colors to use in output (when color is enabled). The  format  for  COLOR_SCHEME  is
              '<debug>:<info>:<warning>:<error>'.  Numerical values and color names are accepted,
              empty fields imply the default color. For  example,  --git-color-scheme='cyan:34::'
              would  show  debug  messages  in  cyan, info messages in blue and other messages in
              default (i.e. warning and error messages in red).

       --upstream-version=version, -uversion
              The upstream version to merge. The upstream tag to use will be determined  via  the
              --upstream-tag.

       --merge-mode=[auto|merge|replace]
              How to fold the upstream commits onto the Debian packaging branch.

              merge  does  a  Git  merge  leaving  you  on  your  own  in  case of merge conflict
              resolution.

              replace mode on the other hand makes  the  head  of  the  Debian  packaging  branch
              identical  to  the  newly  imported  tree  but preserves the content of the debian/
              directory while keeping the current head as well as  the  newly  imported  tree  as
              parents  of  the generated commit. This is similar to a theirs merge strategy while
              preserving debian/.

              The default is  auto  which  uses  replace  for  3.0  (quilt)  packages  and  merge
              otherwise.

       --upstream-branch=branch_name
              The branch in the Git repository the upstream sources are on. Default is upstream.

       --upstream-tag=tag-format
              Use this tag format when looking up upstream tags, default is upstream/%(version)s.

       --upstream-tree=[BRANCH|VERSION|commit-id]
              What  to  merge  into  the  debian-branch.  BRANCH merges from the upstream branch.
              VERSION (the default) looks for a tag determined from the  given  upstream  version
              number via the --upstream-version option.

              Other values are interpreted as git commit id to merge from.

       --debian-branch=branch_name
              The  branch in the Git repository the Debian package is being developed on, default
              is master.

       --[no-]sign-tags
              GPG sign all created tags.

       --keyid=gpg-keyid
              Use this keyid for gpg signing tags.

       --import-msg=msg-format
              Use this format string for the commit message  when  importing  upstream  versions,
              default is New upstream version %(version)s.

       --postimport=cmd
              Run cmd after the import. The hook gets the following environment variables passed:

              GBP_BRANCH
                     The name of the Debian packaging branch

              GBP_TAG
                     The name of the just created upstream tag

              GBP_UPSTREAM_VERSION
                     The just imported upstream version

              GBP_DEBIAN_VERSION
                     The Debian version of the package with a Debian revision of '-1'

       --[no-]rollback
              Rollback changes in case of an error.

EXAMPLES

       Merge  commits  from  the  upstream-branch  into  the debian-branch creating a tag for the
       version 0.0~git20180524:

           gbp import-ref --upstream-tree=BRANCH -u0.0~git20180524

       Merge commits from the the tag corresponding to version 1.0:

           gbp import-ref --upstream-tree=VERSION -u1.0

       Merge commits given by a SHA1 creating a tag for the version 0.0~git20180524

           gbp import-ref --upstream-tree=c4398912c -u0.0~git20180524

CONFIGURATION FILES
