gpp

The Generic Preprocessor

gpp is a general-purpose preprocessor with customizable syntax, suitable for a wide range of preprocessing tasks. Its independence on any programming language makes it much more versatile than cpp, while its syntax is lighter and more flexible than that of m4. gpp is targeted at all common preprocessing tasks where cpp is not suitable and where no very sophisticated features are needed. In order to be able to process equally efficiently text files or source code in a variety of languages, the syntax used by gpp is fully customizable. The handling of comments and strings is especially advanced.
