  • master: Stable;
  • dev: Ocassionally git squash'd, git push --force'd;
  • dev_cache: Constantly git push --force'd.

Developments are mostly done on dev_cache; when they have passed local checks, dev will be git rebase'd to dev_cache, and sent for CI tests. When enough updates have been accumulated, dev will be git squashed into one large commit, followed by having master-branch git rebase'd onto it.


pip install mrphy

(The package is not yet sent to conda.)


Check out files under ./test. After installation, one can quickly play with the tests through:

pytest -s

Only basic demo is available in this early version.
