pepper is a flexible command-line tool for retrieving statistics and generating reports from source code repositories. It ships with several graphical and textual reports, and is easily extendable using the Lua scripting language. pepper includes support for multiple version control systems, including Git and Subversion. Using native language bindings, multi-threading and a local revision cache, it provides fast access to repository data.
