+# Bundle up a directory containing a main python script and some
+# modules into a zip file with a unix python exec header. The main
+# must be named __main__.py (or use symlinks). Method described here:
+# http://blog.ablepear.com/2012/10/bundling-python-files-into-stand-alone.html
+#
+# This does not work under windows, but the comments in the link above
+# have suggestions for windows: use a specific extension and association.
