  ## ### Revision 1.23  1998/12/03 16:46:16  peterg
  ## ### Deblanked attributes so that zero attribute works.
  ## ##
  ## ### Revision 1.22  1998/07/28 19:05:46  peterg
  ## ### Fixed a few bugs.
  ## ##
  ## ### Revision 1.21  1998/07/28 14:21:31  peterg
  ## ### Vector SS ports.
  ## ##
  ## ### Revision 1.20  1998/07/08 14:42:52  peterg
  ## ### Removed the annoying info message - it causes problems with big
  ## ### systems
  ## ##
  ## ### Revision 1.19  1998/07/08 11:33:54  peterg
  ## ### Replace mtt_info by mtt_error when appropriate
  ## ##
  ## ### Revision 1.18  1998/07/08 11:30:45  peterg
  ## ### Removed second (fileID) argument from mtt_info
  ## ##
  ## ### Revision 1.17  1998/07/04 07:15:44  peterg
  ## ### Back under RCS
  ## ##
  ## ### Revision 1.16  1998/04/11 19:07:16  peterg
  ## ### Now do named ports as ordinary ports iff at top level.
  ## ### --- not yet complete, need to pass necesssary info though to this
  ## ###     function
  ## ##
  ## ### Revision 1.15  1997/12/16 19:16:07  peterg
  ## ### Added unknown input to the effort part.
  ## ##
  ## ### Revision 1.14  1997/12/16 18:25:19  peterg
  ## ### Added unknown_input attribure to flow -- effort still needs doing
  ## ##
  ## ### Revision 1.13  1997/09/18 13:15:15  peterg
  ## ### Fixed incorrect error message flagging inappropriate flow outputs
  ## ### -- used to give the effort rather than the flow in the error message.
  ## ##
  ## ### Revision 1.12  1997/08/26 07:51:30  peterg
  ## ### Now counts the local input and outputs by order of appearence rather
  ## ### than by port number - it therfore handles ports with bicausality correctely.
  ## ##
  ## ### Revision 1.11  1997/05/09 08:21:07  peterg
  ## ### Explicit computation of port number -- avoids str2num
  ## ##
  ## ### Revision 1.10  1997/03/22  17:13:03  peterg
  ## ### Fixed bug for port nos. > 1 digit!
  ## ##
  ## ### Revision 1.9  1997/03/22  15:50:59  peterg
  ## ### Changed #1.0f to %d format.
  ## ##
  ## ### Revision 1.8  1996/12/10 16:52:29  peterg
  ## ### Detect null string using strcmp, not length.
  ## ### Put filnum argument to mtt_info.
  ## ##
  ## ### Revision 1.7  1996/12/07 17:17:40  peterg
  ## ### Added some ;
  ## ##
  ## ### Revision 1.6  1996/12/05 09:49:09  peterg
  ## ### Explicit computation of port number from string.
  ## ##
  ## ### Revision 1.5  1996/12/04 21:27:53  peterg
  ## ### Replaced str2num by sprintf
  ## ##
  ## ### Revision 1.4  1996/08/18  20:06:21  peter
  ## ### Included zero outputs.
  ## ##
  ## ### Revision 1.3  1996/08/09 14:08:04  peter
  ## ### Empty effort and flow attributes replaced by 'external'.
  ## ##
  ## ### Revision 1.2  1996/08/08 16:38:19  peter
  ## ### Changed to filenumer type of fprintf
