ViewVC is a browser interface for CVS and Subversion version control repositories. It generates templatized HTML to present navigable directory, revision, and change log listings. It can display specific versions of files as well as difference between those versions. Basically, ViewVC provides the bulk of the report-like functionality you expect out of your version control tool, but much more prettily than the average textual command-line program output. It provide support for path-based authorization, including parsing and honoring Subversion authorize configuration files, RSS feed generation for tracking changes to repositories or individual items within repositories, individually configurable virtual host support, and Line-based annotation or blame display.
