Advanced (python) PSP Scripting: where to start.

As a developer I was curious to learn something about how psp scripts works and at first I was unable to find some documentation to understand how to write / edit a psp script by hand. Like an api references and/or some tutorials.

From the PSP guide I've found out this statement:

Available from the Corel Knowledge Base (accessible from www.support.corel.com) is a document titled Scripting for Script Authors, which contains complete and advanced scripting information for Corel Paint Shop Pro Photo. To find this document, choose Paint Shop Pro from the Products and Services drop-list, then enter script in the Search Text field.

But the url doesn't seems to work and even if I go to http://kb.corel.com I can't find that document..

So I googled a bit and found out the corel ftp site:

ftp://ftp.corel.com/pub/documentation/PSP/

There you can find this useful documents:

• PSPPXICommandAPI.zip (scripting api)
• PSPX Scripting For Script Authors.zip (scripting guide)

p.s.

I've found the right url for corel support for psp scripting:

http://corel.custhelp.com/ - but on this page the PSP XI version of api isn't listed for what I saw. See: Where can I learn more about the Python scripting used in Paint Shop™ Pro®?
