This page contains several assorted projects, which no longer have any relation. They are listed in roughly chronological order (newest first). <strong>Unless specified otherwise</strong>, you may feel free to use and modify both the binaries and any source code, for any purpose, on the general condition you do not misrepresent who the author is (BSD license).

Some of these projects formerly appeared on Google Code <a href="https://code.google.com/p/mappy/">here</a>, but were moved following the discontinuation of the Google Code binary download system.
