Here's what is going on with ACS.

I am in the process of moving it to the GNU site, and calling it 
"GnuCap", the Gnu circuit analysis package.  I have begun to set up 
the support stuff on savannah.gnu.org.  There are 4 mailing lists, 
and CVS will be up soon.  You can get the latest at 
ftp://ftp.gnu.org/gnucap .  There will be a web site on gnu.  For 
now, you can look at the preliminary one at 
http://joule.isu.edu/~aldavis/gnucap/gnucap.html .  That part is 
almost ready for release.  

In development, I have concentrated on the model compiler, which is 
now complete enough that the complete mosfet model (all variants that 
I have) is now done through ".model" files.  The model compiler 
automatically generates the C++ files.  This was the primary block 
for the BJT model.  I could have done BJT without the model compiler, 
but it is a lot less work with it.  The model compiler automatically 
generates most of the simulator specific code.

The 4 mailing lists ......

To subscribe, go to http://savannah.gnu.org/mail/?group_id=562   .
There will be a nicer way to get there when the real web page is up.  
For now, you can go to the temporary one on joule.isu.edu, and click 
"mailing lists".  The lists are archived, but there is nothing in 
them yet because they are new.

For me, the summer was mostly occupied with moving and a new job as a 
professor.  It is a nice location in the mountains.  Yellowstone 
National Park is close enough for a day trip.

As to C++ ...   I remember a few that strongly opposed it, but I they 
haven't particapated in a while.  Switching to C++ resulted in a huge 
improvement in productivity.  I am not going back.  Also, C++ is one 
reason that ACS/GnuCap code size is so much smaller than Spice, even 
though the algorithms are more advanced.
