Installation ============ Mopactools is available on PyPI and can be installed using a standard ``pip install mopactools``. The PyPI distribution includes a copy of the MOPAC shared library. Mopactools will also be available on the conda-forge channel of the Conda package manager in the near future. Otherwise, mopactools can be installed locally from a clone of its GitHub repository using a standard ``pip install .`` command in the root of the source directory. For mopactools to function correctly, it must be able to find the MOPAC shared library in the system path or in the ``lib`` subdirectory of the installed package directory. If a copy of the MOPAC shared library is placed into the ``lib`` subdirectory of the source package, then the ``pip install .`` command will create another copy in the installed package directory.
