+    """ Return extended build command class for recording commit
+
+    The extended command tries to run git to find the current commit, getting
+    the empty string if it fails.  It then writes the commit hash into a file
+    in the `pkg_dir` path, named ``COMMIT_INFO.txt``.
+
+    In due course this information can be used by the package after it is
+    installed, to tell you what commit it was installed from if known.
+
+    To make use of this system, you need a package with a COMMIT_INFO.txt file -
+    e.g. ``myproject/COMMIT_INFO.txt`` - that might well look like this::
+
+        # This is an ini file that may contain information about the code state
+        [commit hash]
+        # The line below may contain a valid hash if it has been substituted
+        during 'git archive' archive_subst_hash=$Format:%h$
+        # This line may be modified by the install process
+        install_hash=
+
+    The COMMIT_INFO file above is also designed to be used with git substitution
+    - so you probably also want a ``.gitattributes`` file in the root directory
+    of your working tree that contains something like this::
+
+       myproject/COMMIT_INFO.txt export-subst
+
+    That will cause the ``COMMIT_INFO.txt`` file to get filled in by ``git
+    archive`` - useful in case someone makes such an archive - for example with
+    via the github 'download source' button.
+
+    Although all the above will work as is, you might consider having something
+    like a ``get_info()`` function in your package to display the commit
+    information at the terminal.  See the ``pkg_info.py`` module in the nipy
+    package for an example.
