I have a wiki set up at, but there is nothing on it 
yet.  It is running dokuwiki, chosen mainly because that is the 
one that gEDA uses, which should make it easy to mirror there.  
Since there is nothing there yet, the choice is not firm.

Formal bug tracking is probably a good idea, but it has not been 
a problem.  The number is bugs is low compared to most 
projects, and most get fixed immediately when they are 
discovered.  There are built-in checks in the code for many 
potential problems.  The code not checked adequately by the 
regression suite is documented.  Almost all bug reports 
received so far are related to a user error.  In this case, the 
bug (or bugs) are usually in the error handling code, which is 
tested less rigorously than the mainline code.  Gnucap uses 
structured exception handling, which makes error handling much 

Another issue in a simulator is that the algorithms are not 
perfect, sometimes causing trouble for the user.  By this, I 
mean there are inherent deficiencies that are not bugs, but 
rather just the way the algorithm works.  For example, it is 
known that the Newton-Raphson method does not always converge.  
Another example, it is known that certain time step issues can 
show artifacts of numerical differentiation.

There is something set up at  I have not used it yet.
