The package defines a command \includedoc, which allows you to include just the contents of one source file into another, ignoring text outside \begin{document} ... \end{document} in the included file. In other respects, the command behaves like the standard LaTeX command \include.

The package is not supported, and is distributed as one of the frankenstein bundle’s ‘appendices’. The package’s functionality is now provided by the newclude package.
