By the way, I wonder how to find the open sources of Construct.
I'm interested in GPL, etc.
Take a look here: http://sourceforge.net/projects/construct/develop
Construct uses Subversion, a version control system to maintain its code. I'm a Linux guy so I prefer to type in the commands, but if you don't feel comfortable in doing that, you should use either RapidSVN or TortoiseSVN. Some IDEs also have SVN built in.

Erm, what? Freeware means free to use, not necessarily free to use for commercial purposes.
Yes, that is correct, but GPL allows for free use for commercial purposes. GPL basically states that any modifications or projects based on the code has to be released under GPL as well but that anything created using the GPL application is free to be licensed under any license including commercial licenses.
