1. Current Version: 2.11a Tue Mar  6 09:46:16 EST 2001

   (an [a-z] suffix to your version number indicates that you have
   received a beta copy of the next release).

2. The Simple Sockets Library, developed at NASA's Goddard Space Flight Center
   by the U.S. Government, is public domain, and therefore may be copied and
   distributed freely.

3. You should have the following files:

4. Check out <rdcolor.dat> for better use of color terminals.  If your sktdbg,
   for example, appears in monochrome, you may have to modify <rdcolor.dat> to
   support your terminal.  Some machines (such as PCs) may not have the
   environment variable TERM set.  More info on this is in <sockets.tex>.

6. Good Luck!  Let NASA know how much you appreciate the Intelligent
   Robotics Laboratory, Robotics Branch, Goddard Space Flight Center!
             (: well, I *hope* you appreciate us! :)

   :( Sigh, too late ... Goddard has axed its Robotics Branch. ):
