a documentation system that uses a single source to produce both on-line information (info, html, xml) and printed output (dvi, pdf)
The goal of tidydoc is to make documentation organization easier. It makes it easy to add documents to a pool of documents, give them the right names, put them into the right directories, and generate a set of HTML pages to browse your documents. Documents can be added or manipulated through a web interface or command line scripts.
