With the example you gave above, it's anything *but* universal.  Both Storm
and Mandrake are RedHat derivatives.

However, I would like to point out that my Debian Potato installation has
COLUMNS defined.  It would be more useful if it also had a ROWS variable set
up as well.  :)

The question I'd like to know is, is this a POSIX requirement at all?  That
might prove to be useful research for when targetting applications that
require knowledge of terminal width.
