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.
