### Including a file verbatim in LaTeX

A good way is to use Rainer Schöpf's verbatim, which provides a command `\verbatiminput` that takes a file name as argument.

Another way is to use the `alltt` environment, which requires alltt. `alltt` interprets its contents 'mostly' verbatim, but executes any TeX commands it finds: so one can say:

      \begin{alltt}
      \input{verb.txt}
      \end{alltt}

of course, this is little use for inputting (La)TeX source code...

Moreverb extends the facilities of verbatim package, providing a `listing` environment and a `\listinginput` command, which line-number the text of the file. The package also has a `\verbatimtabinput` command, that honours TAB characters in the input (the `listing` environment and the `\listinginput` command also both honour TAB).

The fancyvrb package offers configurable implementations of everything verbatim and moreverb have, and more besides. It is nowadays the package of choice for the discerning typesetter of verbatim text, but its wealth of facilities makes it a complex beast and study of the documentation is strongly advised.
