geomm
is very easy to build yourself. See the developers
instructions to do so.
You can also install from the source package on PyPI.
geomm
was started by Samuel Lotz in Alex Dickson’s group at Michigan
State University, and is maintained there. You can email any member of
the lab from the website: https://www.egr.msu.edu/~alexrd/.
Otherwise just use the issue tracker.
