## Revision 1.11.2.3  2002/06/05 18:23:38  geraint
## Cosmetic change.
##
## Revision 1.11.2.2  2002/06/05 17:57:47  geraint
## Main part of optimisation routine moved to separate file.
##
## Revision 1.11.2.1  2002/06/05 11:14:51  geraint
## ae.r now generated using def2write_r like cse?.r
## fix_c.r called at ese2rdae stage so that pow gets fixed in ae.r.
