The virtual TextUpload plugin allows to insert new WikiPages+ by
uploading text files. It can convert from various formats into Wiki
content, including some proprietary Office file formats, if one of
the possibile filters is avaiable (Unix style file piping).
It also can extract multiple files from a Tarball or ZIP archive
if the according utilities are available (even on DOS/Win systems).

You cannot modify the README.plugins file, but anyhow any ideas or suggestion should as usually get filed on BugReports, UserSuggestions or even better the README.plugins.Discussion.
