Another real good source for BSD compatible ports, packages and pointers 
is the FreeBSD organization  at <http://www.FreeBSD.org> or 
<ftp://ftp.FreeBSD.org>.  They have over 400 packages indexed, 
catagorized, documented and available through Hot Links on their Ports 
and Packages pages.  Many also have patches that have been worked up for 
use on FreeBSD which, like NetBSD, is a BSD derived system which helps in 
porting them to NetBSD.  There are pointers to tvwm, fvwm, and cvwm in 
their X-Applications Folder (oops, they're Intel based so that should be 
X-Applications Directory).
