michael@0	6
michael@0	7	``mozinfo`` is a solution for representing a subset of build
michael@0	8	configuration and run-time data.
michael@0	9
michael@0	10	``mozinfo`` data is typically accessed through a ``mozinfo.json`` file
michael@0	11	which is written to the :term:`object directory` during build
michael@0	12	configuration. The code for writing this file lives in
michael@0	13	:py:mod:`mozbuild.mozinfo`.
michael@0	14
michael@0	15	``mozinfo.json`` is an object/dictionary of simple string values.
michael@0	16
michael@0	17	The attributes in ``mozinfo.json`` are used for many purposes. One use
michael@0	18	is to filter tests for applicability to the current build. For more on
michael@0	19	this, see :ref:`test_manifests`.
