# this script looks for the presence of /tmp/svardos_repo_changed.flag file
# and rebuilds the packages index if it exists (then deletes the flag).
#
# it is supposed to be called periodically from within a cron job.
#
# the /tmp/svardos_repo_changed.flag file is expected to be created by an
# svn post-commit hook whenever something in the svn repo changes.
#
# bash is required because I use the internal bash "read" command.
