   3 # this script is meant to run as an Arch post-commit hook (and also as a
   4 # pre-commit hook), using the "arch-meta-hook" framework. See
   5 # http://wiki.gnuarch.org/NdimMetaHook for details. The pre-commit hook
   6 # creates a list of files (and log comments), while the post-commit hook
   7 # actually notifies the buildmaster.
   8
   9 # this script doesn't handle partial commits quite right: it will tell the
  10 # buildmaster that everything changed, not just the filenames you give to
  11 # 'tla commit'.
