Get the current git hash of a project and typeset it in the document
Description
This package will get a description of the current git version
of the document and store it in a command \gitVer. If memoir or
fancyhdr are in use, it will also add this to the document
footers unless the option "noheader" is passed. The package
also defines a command \versionBox which outputs a box
containing the version and date of compilation.
