   1 """Create a standalone application from a Python script.
   2
   3 This puts up a dialog asking for a Python source file ('TEXT').
   4 The output is a file with the same name but its ".py" suffix dropped.
   5 It is created by copying an applet template, all used shared libs and
   6 then adding 'PYC ' resources containing compiled versions of all used
   7 modules written in Python and the main script itself, as __main__.
