## MTT is now much more sophisticated in generating lbl files
## Labels can contain maths
## Repetative components are now broken

## Revision 1.15  2001/06/11 16:53:49  gawthrop
## Now uses abg2sympar_m2txt to get the arguments
##
## Revision 1.14  2001/06/11 15:06:58  gawthrop
## Now handles user-defined components
