1	n/a	/* OS/2 PM main program - creates a hidden window, and starts Python
2	n/a	* interpreter in a separate thread, so that Python scripts can be
3	n/a	* run in PM process space without a console Window. The interpreter
4	n/a	* is incorporated by linking in the Python DLL.
5	n/a	*
6	n/a	* As it stands, I don't think this is adequate for supporting Python
7	n/a	* GUI modules, as the Python thread doesn't have its own message
8	n/a	* queue - which is required of threads that want to create/use
9	n/a	* PM windows.
10	n/a	*
11	n/a	* This code owes a lot to "OS/2 Presentation Manager Programming", by
12	n/a	* Charles Petzold.
