+# What is this script?
+#
+# Chef Workstation uses Expeditor to manage the bundled version of the
+# Chef Workstation App. Currently we always want to include the latest version 
+# of Chef Workstation App inside Workstation, so this script takes that version
+# and uses sed to insert it into the omnibus project definition. Then it commits
+# that change and opens a pull request for review and merge.
