`chpp’ is a preprocessor. Therefore, its main purpose is to modify input text by including other input files and by macro expansion.

What distinguishes `chpp’ from other textprocessors are mainly two features

  • chpp' is non-intrusive. This means that you can take your favorite text and it is very unlikely that it will be changed when piped through chpp’. Due to this feature it is pretty easy to start using chpp' since you can just start writing your text and need not concern yourself with chpp’ sitting in the background changing it for no obvious reason.

  • `chpp’ is not just a package for performing simple macro expansion, but can indeed be considered a full-fledged programming language. Most importantly, it provides support for complex data structures, namely lists and hashes associative arrays, which can be nested arbitrarily.
