"""Create an applet 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 and then adding a 'PYC '
resource named __main__ containing the compiled, marshalled script.
