""" 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 ``.git_commit_info.ini``.
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 .git_commit_info.ini
file - e.g. ``myproject/.git_commit_info.ini`` - 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 .git_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/.git_commit_info.ini export-subst
That will cause the ``.git_commit_info.ini`` 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.
