mod_macro is a module that allows the definition and use of macros within Apache runtime configuration files. The syntax is a natural extension to Apache HTML-like configuration style. It's very useful if you have to configure many sections (e.g., when you have many virtual hosts) and haven't learned about <Perl>sections yet.
mod_macro is available from http://www.cri.ensmp.fr/~coelho/mod_macro/.
