BAD NEWS
This module is dirty approximation to the features of FreeBSD's
libdialog. It's poor and nasty. Please, don't consider it works
at all.
GOOD NEWS
It really works. Volgalink Co. (http://www.vlink.ru/) uses it
for it's own purposes for three or even more years
BAD NEWS AGAIN
It's being compiled on FreeBSD only. Linux and others are
coming.
MAYBE GOOD
If somebody ported libdialog to, say, Linux, it would mean that
you got this OS supported.
