% License: LaTeX Project Public License 1.3c
%
% This package will get a description of the current git version of this
% document and store it in a command "\gitVer". If memoir is installed, it
% will also add this to the document headers unless the option "noheader" is
% passed.
%
% It also defines a command "\versionBox{}" which outputs a box containing the
% version and date of compilation
%
% For this to work, you must have git installed and available on the command
% line, and latex must be running in "shell escape" mode.
