The major contributors to pcvt are Brian and Joerg, pcvt would not be what it
is without the help, the support and the code from Joerg:

                            Brian Dunford-Shore           (brian@athe.wustl.edu)

                            wrote parts of the EGA/VGA hardware handling and
                            some of the more ugly aspects of the VT220.

                            Joerg Wunsch        (joerg_wunsch@uriah.heep.sax.de)

                            added ALL support for XFree86, the screensaver sub-
                            system and support for FreeBSD (and much more ...).


I have to thank the following people for their help, for beta-testing, bugfixes,
code, keymaps, suggestions, hints, patience and too much more to mention:
