From a03adde31b148fee3f3c1a5b24e99d66e7ee750d Mon Sep 17 00:00:00 2001
From: Jack Jansen <jack.jansen@cwi.nl>

Subject: [PATCH] Added an argv_emulation option (command line option: --argv
 or -a) which creates the sys.argv emulation wrapper for droplets. Also
 updates the plist, if needed, and the includedModules (but this last is
 untested).
