# wpp(1)

The Web Preprocessor

## NAME

WPP - The Web Preprocessor

## SYNOPSIS

**wpp** \[POSIX or GNU style options\] file ...

## DESCRIPTION

WPP is a small perl5 script that allows preprocessing of html files. It's useful for giving an uniform layout to different html pages. It allows you to define "variables", which are abbreviations for longer constructs, and include common html fragments.

WPP provides four separate facilities that you can use as you fit: inclusion of templates, variables expansion, conditional generation and macro expansion.

It can be used into cgi scripts for dynamic generation of pages. With less html code inside them you can make more flexible and readable cgi-scripts.

WPP is distributed under the terms of the GNU General Public License (GPL). As such, you can use this program free of charge but there is no warranty.
