A '''preprocessor''' is tool that is used to transform a program's source code before feeding it into the compiler or interpreter that implements a particular language. Some languages ([C], [C++], [Ratfor]) are strongly dependent on their preprocessors. Tcl is not normally used that way. ** Tcl preprocessors ** * [Assemble (tool)] * [tpp] * [Tipi] * http://www.gener8.be/site/downloads/index.html%|%g2pp%|% * [c-like preprocessor facility] <<categories>>Concept|Glossary|Dev.
