+:mod:`mozinfo` --- Get system information
+=========================================
+
+Throughout `mozmill <https://developer.mozilla.org/en/Mozmill>`_
+and other Mozilla python code, checking the underlying
+platform is done in many different ways.  The various checks needed
+lead to a lot of copy+pasting, leaving the reader to wonder....is this
+specific check necessary for (e.g.) an operating system?  Because
+information is not consolidated, checks are not done consistently, nor
+is it defined what we are checking for.
+
+`mozinfo <https://github.com/mozilla/mozbase/tree/master/mozinfo>`_
+proposes to solve this problem.  mozinfo is a bridge interface,
+making the underlying (complex) plethora of OS and architecture
+combinations conform to a subset of values of relevance to
+Mozilla software. The current implementation exposes relevant keys and
+values such as: ``os``, ``version``, ``bits``, and ``processor``.  Additionally, the
+service pack in use is available on the windows platform.
+
+
+API Usage
+---------
+
+mozinfo is a python package.  Downloading the software and running
+``python setup.py develop`` will allow you to do ``import mozinfo``
+from python.
+`mozinfo.py <https://raw.github.com/mozilla/mozbase/master/mozinfo/mozinfo/mozinfo.py>`_
+is the only file contained is this package,
+so if you need a single-file solution, you can just download or call
+this file through the web.
+
+The top level attributes (``os``, ``version``, ``bits``, ``processor``) are
+available as module globals::
+
+    if mozinfo.os == 'win': ...
+
+In addition, mozinfo exports a dictionary, ``mozinfo.info``, that
+contain these values.  mozinfo also exports:
+
+- ``choices``: a dictionary of possible values for os, bits, and
+  processor
+- ``main``: the console_script entry point for mozinfo
+- ``unknown``: a singleton denoting a value that cannot be determined
+
+``unknown`` has the string representation ``"UNKNOWN"``.
+``unknown`` will evaluate as ``False`` in python::
+
+    if not mozinfo.os: ... # unknown!
+
+
+Command Line Usage
+------------------
+
+mozinfo comes with a command line program, ``mozinfo`` which may be used to
+diagnose one's current system.
+
+Example output::
+
+    os: linux
+    version: Ubuntu 10.10
+    bits: 32
+    processor: x86
+
+Three of these fields, os, bits, and processor, have a finite set of
+choices.  You may display the value of these choices using
+``mozinfo --os``, ``mozinfo --bits``, and ``mozinfo --processor``.
+``mozinfo --help`` documents command-line usage.
