I'd just like to point out that Bill has reworked datadraw so that you 
can build the whole tool from source on linux/netbsd/solaris/whatever 
now.  In years past, one complaint was that the datadraw frontend was a 
windows gui and it made it a bit of a pain for non-windows users.  This 
is no longer an issue.

The upshot is datadraw is now a viable option for someone wanting to 
work on large scale netlist and other eda database manipulator programs.
