Writing software requirements specifications as XML documents has quite a few advantages. Using open source tools like Emacs, PSGML, CVS and xsltproc gives us a powerful Requirements Engineering tool.
- Gather information using Emacs
- Validating specifications using psgml and XSLT
- Keeping track of changes using CVS and XSLT
- Creating nice output with xsltproc
- Transforming requirements data to project management tools

Subversion is an open source version control system. Subversion was originally designed to be a better CVS, so it has most of CVS's features. Generally, Subversion's interface to a particular feature is similar to CVS's, except where there's a compelling reason to do otherwise.
Subversion has since expanded beyond its original goal of replacing CVS, but its history influenced its feature and interface choices; Subversion today should still feel very familiar to CVS users.
