The Amboseli Baboon Research Project runs Babase on Linux. Any Unix based OS, including Mac OS/X should run Babase with little difficulty. Babase will probably run on Microsoft Windows as well. All components of the runtime environment are cross platform but the build environment is Unix based so it will probably take something like Cygwin to install Babase on Microsoft Windows.

Moinmail is a framework for administering a system that automatically generates mail at regular intervals using the moinmoin wiki as the management interface. It was developed to support Babase but is completely independent.
