At my work, we have to add some sort of revision history to certain documents. This is also an example for the use of \getparameters (see Commands with KeyVal arguments).

A downloadable version of the macro is available here, and a PDF example of the output here.

Note that background=screen is depricated and should be replaced by something like background=color,backgroundcolor=gray.
