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