+""" This module can serve as a startup script to play a Panda
|
|
|
|
|
+application packed within a .mf file. Run via:
|
|
|
|
|
+
|
|
|
|
|
+python StartMF.py app.mf
|
|
|
|
|
+
|
|
|
|
|
+This is currently experimental, but the intent is to work towards a
|
|
|
|
|
+prepackaged Panda distributable, designed to run applications exactly
|
|
|
|
|
+like this.
