   #  Felt strongly enough about hoisting ReadConfiguration into a separate sub

   #  Revision 1.10  2003/08/18 10:43:31  foxr
   #  Code/test ValidHost.  The hosts.tab and the perl variables are read in as
   #  global hashes as a side effect.  May later want to clean this up by making
   #  a separate getconfig function and hoisting the config reads into that.
