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