As so often, there is hardly anydocumentation. The available documentation of the Python classes and methods can by access by using the pydoc program. The source tar ball contains a directory with some example scripts, which I used to test various bits of the wrapper.
tar xvzf PyGMT-0.0.tar.gz
./setup.py install --home=DIR_WHERE_YOU_WANT_THE_STUFF_TO_GOUse --home to specify a non-standard installation directory. If you do that, you will need to set the environment variable PYTHONPATH to point to this directory in order for python to find the module. Furthermore, the netCDFlibrary is required. setup.py looks for the header files in the standard locations, i.e. /usr/include and /usr/local/include.
python test_areaxy.pyThese scripts should also give a first impression how PyGMT might work. Hopefully, I will get around to add some more documentation.
