# inn-snapshot -- Generate nightly INN snapshots.
#
# This is my local script to generate nightly INN snapshots and save them into
# the appropriate directory, only keeping the last seven valid snapshots.
# Most of the work is done by the snapshot script in the INN distribution, but
# a wrapper is needed to handle Subversion checkouts and putting the resulting
# tarball in the right place.
