+# this script is designed to be run under sudo by

+# It checks the validity of the current apache config and
+# then updates one vhost config from the staging area that
+# is writeable by the user.

+# This script ensures that the resulting apache config is then
+# still syntactically valid and reloads apache. If the new config
+# is not OK then the change is reverted.

+# All config changes are tracked in RCS.

+# needs something like this in sudoers:
# %apachectrl ALL=(root) /usr/sbin/restart-apache
