HTML preprocessor. (HTML Sucks Completely)
HSC is an HTML pre-processor, ie. it reads files written in a pseudo-HTML format and converts them in proper HTML files by performing various operations. In particular, it performs a limited syntax check, tests the presence of local links, images, etc., strips useless white-spaces and, most importantly, provides a powerful way of defining HTML-like macros. This is particularly useful to keep a consistent style across a number of pages and saves time when things must be changed globally.
