newbie questions about setting up a new project

I've found part of the problem. There is a "projects" directory (including a "sample" subdirectory) inside the folder where I built LLVM, but there is ALSO one inside the llvm-2.2 directory. And they are different. I was working with the former, which contains no source code; the sample project under llvm-2.2 actually includes a main.c and sample.h, and generally makes a lot more sense. (The one in my build directory didn't even have an "include" folder; I created that based on the docs, but now I see I was barking up the wrong tree all along.)

So, in such a situation where LLVM was not built in its own source directory, which "projects" folder should be used for my own projects?
