yaktest is a simple C++ unit testing framework. It has its roots in the JUnit testing framework for Java, but is implemented in a much simpler fashion. Additionally, its output is Emacs-compatible, so adding a "test" target in a makefile makes for fairly simple automated unit testing, with failures directed to the offending line number. An example is included in the source and .gz distributables.
YakTrack is a simple but reasonably effective issue-tracking system written in Python using the current XML libraries. It uses simple XML DTDs to define issue formats, and stores each issue as a separate XML file, making for a very simple database structure. A command-line interface is available which either generates a series of textual prompts or shells out to an external editor to edit or submit new issues, query the database, etc. An email gateway and a CGI interface are also available.
