"""Specialized class for packages that are built using editable Makefiles
This class provides three phases that can be overridden:
1. :py:meth:`~.MakefilePackage.edit`
2. :py:meth:`~.MakefilePackage.build`
3. :py:meth:`~.MakefilePackage.install`
It is usually necessary to override the :py:meth:`~.MakefilePackage.edit`
phase, while :py:meth:`~.MakefilePackage.build` and
:py:meth:`~.MakefilePackage.install` have sensible defaults.
For a finer tuning you may override:
