MSVC resource script in Dev-C++

Hi All,
I have ported a text editor called NoteXpad2 from MSVC to a Dev-C++ project. It works fine, but now im tweaking it for my own nefarious purposes (well, maybe not so nefarious, but its a cool word).
All of the dialogs and the menu structure are defined in a file named NoteXpad2.rc. It is a resource file and has MSVC headers. I believe it is automatically generated by MSVC? Maybe not, just a guess.

I have 2 questions:
1) Is there some other gcc format I should port this over too when time allows? Or would that mean coding them all from scratch?

2) Where can I find documentation on the keywords and format for this so I can change it to meet my own purposes? I can get a lot from following whats already there, but there are some things I want to do that I dont have samples for.

Thanks
-Josh
