unfinished, untested, unsupported, ...

Well, more or less everything I offer deserves attributes like unfinished but for the packages here it's even worse: I also do not necessarily intend to fix remaining problems, so I don't call them previews ...
They may come in incomplete packages, often lacking all original documentation and without any OS/2 specific docs. So don't download them if you don't know what you're doing :-)

  Bugyy, I know. Ignore the error messages and try editing/reading a sample RTF document.
  May call a few utils (ls, ...). You better have them around ;-)
