Pharmpy is a library and toolkit for pharmacometrics. It can be used as a regular python package, in R
via the `Pharmr <https://github.com/pharmpy/pharmr>`_ package or via its built in command
line interface.

Current features:

* A model abstraction as a foundation for higher level operations on models
* Functions for manipulation of models, e.g. changing model components like elimination or absorption
* Reading NONMEM models and results
* Running models and complex workflows (with NONMEM or to some extent nlmixr)

This is the `team behind Pharmpy <https://pharmpy.github.io/latest/contributors.html>`_
