My name is Bob Techentin.  I am signing my Wiki posts as ''RWT''.

I work for a research group at the Mayo Clinic in Rochester Minnesota.  We build fast (10,000 MHz+) digital electronics.  My work involves developing electromagnetic modeling simulators to help us design those systems.  Lately I've been integrating a Tcl interpreter into the simulator using SWIG [http://www.swig.org].  Our home page is http://www.mayo.edu/sppdg/sppdg_home_page.html , and 
my work email address (which I read just about every business day) is mailto:techentin.robert@mayo.edu .

My personal email address is mailto:bob@techentin.net , and I
maintain some "stuff" at http://www.techentin.net/ , including
some Tcl material.  That web site, by the way, was created using
Don Libes' cgi.tcl package [http://expect.nist.gov/cgi.tcl/]
