That should be harmless. However, my Cygwin installation (which hasn't
been updated, or even used, in about a year) has a "clear" command
(it's in its own package).

You need an X server in order to use tcltkgrass or NVIZ. XFree86 is
available for Cygwin, although the last time that I tried it was
definitely "beta" quality.

I'm not sure that tcltkgrass is really worth the effort of installing
XFree86. Unless you want to use NVIZ (in which case, and X server is
necessary), you may as well stick to the command-line interface.
