Various LaTeX classes. Note that some of this exists as independent LaTeX repostiories (e.g., ouexam, beamerthemes). These are included as submodules.

To update:, ensure that $TEXMFHOME is set to your personal texmf tree (e.g., ~/.texmf), then:

cvs update
make install

Everything should just work beyond that point (fingers crossed!), barring any backwards incompatible changes to classes or the like.
