[S] Homogeneity of Covariance Matrices

Before I attempt to re-invent the wheel, are there any routines out there
that implement a test for homogeneity of covariance matrices? I've looked
in all the obvious places (manuals, VR, cmu) but don't see anything that
looks like it actually does something like Box's M (SPSS) or Anderson's
modification of Box's M (SAS), or the graphical techniques found in Systat.

Suggestions and/or pointers welcomed.
