+# This script is very slow.
+# Hence the option to use find's -newer.
+# A file can be created before stagit runs,
+# and this script will only modify files created after.
+#
+# stagit will not modify files in the commit/ dir once created
+# It does however recreate everything at HEAD.
+# This isn't ideal.
+#
+# Most of the time taken in this script is most likely NOT cpu time.
+# It may be a good idea to run the main loop portion of this script in parallel.
