   4 # When $GIROCCO_DIVERT_GIT_SVN_AUTO_GC is set to 1
   5 # that hook, when executed, runs this script and
   6 # no matter what exit code this script uses, the
   7 # pre-auto-gc hook always exits with a code of 1
   8 # immediately after this script finishes thereby
   9 # aborting any Git-directed gc.

  11 # The `git-svn fetch` operation periodically runs
  12 # `git gc --auto` which ultimately causes this
  13 # script to run provided the correct conditions
  14 # are met and $GIROCCO_DIVERT_GIT_SVN_AUTO_GC is
  15 # set to 1 in the environment.
  16
  17 # Both the jobd/update.sh and taskd/clone.sh scripts
  18 # set and export GIROCCO_DIVERT_GIT_SVN_AUTO_GC=1
  19 # and force `gc.auto=1` as well whenever they process
  20 # a `git-svn` mirror.
