+# stg-gitk - helper script to graphically display an StGIT stack
+
+# Allows quick synchronization of a cvs mirror branch (does not try to
+# reconstruct patchsets, creates "jumbo" commits), and commits stgit
+# patches to CVS.
+
+# LIMITATIONS:
+# - asking gitk to "update" won't detect any new ref
+# - no support for spaces in branch names
+
