A collection of verbatim facilities that provide line-numbered
verbatim, verbatim that obey's TAB characters, verbatim input and
verbatim output to file. The package makes use of the LaTeX required
verbatim package. The package formed from a series of small pieces,
and is somewhat unstructured. The user who looks for thought-through
verbatim facilities is advised to consider using the fancyvrb package
in place of moreverb.
