add source file to clang project??

Hi all,
I am new to the list and have been lurking a few days. I want to add some source file(.h,cpp) to the clang.
How do I modify the project file in clang.xcodeproj when I work on linux.

thanks for you help.

I just wouldn't worry about it. People using MSVC or Xcode are expected to update their projects as the source base changes.
