tabverb – Verbatim text respecting TAB characters
The (LaTeX 2.09) package provides a version of the verbatim environment that respects TAB and FF (control-L) characters; the space between tab-stops is programmable. A \inputverbatim command is also available.
Note that the facilities of this package (apart from FF support) are provided by the LaTeX 2e package moreverb.
