+#!/bin/bash
+
+# script to update apache site configs
+#
+# this script is designed to be run under sudo by
+# the maintainers of our various apache2 vhosts.
+#
+# 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/apache2-vhost-update
