+"""Validate and add a new item to the Invirt build queue.
+
+This script, intended to be invoked by remctl, first validates the
+build submitted parameters, and then adds a new item to the
+Invirtibuilder build queue, triggering the Invirtibuilder to start the
+build.
+
+The expected arguments are
+
+  pocket package commit
+
+This script will also automatically extract the Kerberos principal
+used to submit the job, and include that in the queue file for records
+keeping.
