## Version control history
###############################################################
## $Id$
## $Log$
## 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.
##
## These changes produce the desired result (optimised algebraic equations) but
## have highlighted a problem; when optimisation fails, Reduce does not write
## a result. For complicated systems, this can lead to missing assignments in
## the resultant code.
##
## Revision 1.11  2002/05/17 09:14:58  geraint
## Optimises each line in a separate session. Allows larger models to be built.
##
## Revision 1.10  2002/04/28 18:41:27  geraint
## Fixed [ 549658 ] awk should be gawk.
## Replaced calls to awk with call to gawk.
##
## Revision 1.9  2001/07/27 23:29:10  geraint
## Optimises only when requested (-opt).
