## Revision 1.45  2004/04/07 12:17:43  gawthrop
## Handles new Fig header line.
##
## Revision 1.44  2002/05/25 09:23:47  gawthrop
## Self-naming components: name is mttTYPE or mttTYPE_2 ...
##
## Revision 1.43  2002/05/22 10:33:18  gawthrop
## Nameless components are now named according to type - replaces old
## mtt1 etc style.
##

#		field  3 is the CR arguments
#  	The fig file represents components by 14 fields
#             field 1 = 4
#		fields 12 and 13 are the coordinates
#		field 14 is the type:name string terminated by \001
# To prevent text being confused with components, components consist
# of alphanumeric characters and : and _ only.
# 
# Components are sorted alphabetically ("type:name")
# within the following categories:
# 1) internal ports (SS:[...])
# 2) basic components, subsystems and external ports 
# 3) 0 junctions
# 4) 1 junctions
