# 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.
