I'm new to XCode and Mac OS in general, and I had a brief question regarding syntax coloring. I apologize if this is not the correct location to post this question, but I've seen similar discussion in this thread so I hope it's at least semi-appropriate.

Basically, I'm using a file type (.g file) that is not recognized by the Xcode editor. Thus, every time I open one of these files in Xcode, it uses the basic syntax coloring which is not useful for me. I've found that C++ works well for my needs, but the problem is that every time I open a file, I need to manually work through the menus and select this option. Is there any way I can tell the Xcode editor to automatically recognize .g files and assign the C++ coloring scheme to them in the editor?

I know other editors like Textwrangler can do this, but I've scoured the preference menus in Xcode to no avail. Any advice would be appreciated

Thanks!

PS - I am using a Macbook pro with Snow Leopard and a freshly installed version of Xcode.
