Writing a standalone c preprocessor (like the old cpp) using the cpplib

[Oliver Rohe]

Hi everybody,

for a project I need a standalone c preprocessor and I was thinking about using 
the cpplib from the latest gcc-core 4.6 snapshot
as the base library. Could maybe anyone please post a very brief guide on how to 
start and what files I have to look at. I am quite a beginner
and kinda lost without some help. My idea is to write a frontend that reads in 
the files, include paths and the defines, then calls the libcpp to do
the preprocessing and afterwards writes out the preprocessed files.

I hope someone can give me some infos...
Thanks in advance,
Oli
