## Revision 1.11 2001/07/06 00:46:50 gawthrop
## Added -cr option -- forces cr to be loaded before the ese.r file
## This avoids causality problems when using multi-port Rs to represent
## arbitary equations

## Revision 1.10 2000/11/30 15:23:16 peterg
## Taken out all subsystem stuff - now done in mtt using

## Revision 1.12.2.1 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 1.12 2001/07/23 23:31:17 gawthrop
## Added -cr option to load CRs first - avoids alg. loops with R
## implementation of mutiports.
