   Revision 1.4  1999/02/02 09:54:26  rjmcnab

   Changed the configuration file reader so that any space can be used to
   seperate items and so that quotes can be used to contain items. I also
   allowed a '\' to indicate that the line continues on the next line.

   Revision 1.3  1999/01/12 01:50:57  rjmcnab

   Standard header.

   Revision 1.2  1999/01/08 02:33:13  rjmcnab

   Added standard header to source files.
