This script calls the UNIX man command.
It is usefull for sites that have access to FTP
but not Telnet. This script makes it easier to
read man pages even on those sites with Telnet.
Many man entries are lengthy and require you to
use more or pg filters, and you can't page back.
It was developed and tested at communitech.net that
runs SunOS, please note the code that removes the
headings you may have delete or modify those lines.
It also removes blank lines. There is no error
trap so missing man pages are retunred blank.
