"""Create a standalone application from a Python script.

This puts up a dialog asking for a Python source file ('TEXT').
The output is a file with the same name but its ".py" suffix dropped.
It is created by copying an applet template, all used shared libs and 
then adding 'PYC ' resources containing compiled versions of all used 
modules written in Python and the main script itself, as __main__.
