Over the time, PTGUI has changed its script syntax. To add support 
reliably, I need access to examples of different versions.

A typical PTGui script starts with:

-----------
# ptGui project file

#-fileversion 8
-----------

I have examples for version 4 and 8.
I need examples of the other versions as well. Please send them to so I 
can add a working script import.
