"""Add a 'PYC ' resource named "__main__" to a resource file.
|
||||
|
||||
This first puts up a dialog asking for a Python source file ('TEXT'),
|
||||
then one asking for an existing destination file ('APPL' or 'rsrc').
|
||||
|
||||
It compiles the Python source into a code object, marshals it into a string,
|
||||
prefixes the string with a .pyc header, and turns it into a resource,
|
||||
which is then written to the destination.
|
||||
|
||||
If the destination already contains a resource with the same name and type,
|
||||
it is overwritten.
