The CodeDoc class is an alternative to DocStrip (and others) to produce LaTeX code along with its documentation without departing from LaTeX's ordinary syntax.

The documentation is prepared like any other LaTeX document and the code to be commented verbatim is simply delimited by an environment. When an option is turned on in the class options, this code is written to the desired file(s).

The class also includes fully customizable verbatim environments which provide the author with separate commands to typeset the material and/or to execute it.
