+===============
+mozconfig Files
+===============
+
+mozconfig files are used to configure how a build works.
+
+mozconfig files are actually shell scripts. They are executed in a
+special context with specific variables and functions exposed to them.
+
+API
+===
+
+Functions
+---------
+
+The following special functions are available to a mozconfig script.
+
+ac_add_options
+^^^^^^^^^^^^^^
+
+This function is used to declare extra options/arguments to pass into
+configure.
+
+e.g.::
+
+ ac_add_options --disable-tests
+ ac_add_options --enable-optimize
+
+mk_add_options
+^^^^^^^^^^^^^^
+
+This function is used to inject statements into client.mk for execution.
+It is typically used to define variables, notably the object directory.
+
+e.g.::
+
+ mk_add_options AUTOCLOBBER=1
+
+Special mk_add_options Variables
+--------------------------------
+
+For historical reasons, the method for communicating certain
+well-defined variables is via mk_add_options(). In this section, we
+document what those special variables are.
+
+MOZ_OBJDIR
+^^^^^^^^^^
+
+This variable is used to define the :term:`object directory` for the current
+build.
+
+Finding the active mozconfig
+============================
+
+Multiple mozconfig files can exist to provide different configuration
+options for different tasks. The rules for finding the active mozconfig
+are defined in the
+:py:func:`mozboot.mozconfig.find_mozconfig` method.
+
+.. automodule:: mozboot.mozconfig
+ :members: find_mozconfig
+
+Loading the active mozconfig
+----------------------------
+
+.. autoclass:: mozbuild.mozconfig.MozconfigLoader
+ :members: read_mozconfig
