Download MDSplus sources

The MDSplus source code is maintained on github. If you are interested in building MDSplus from the sources we recommend downloading a tarball, or a zip file from there.

1. choose 'stable' or 'alpha' - ""note alpha is the active development branch and may contain untested code.""
2. choose 'zip' or 'tar.gz'
3. download the sources (choose one of):
