Dear Maintainer,
I'm invited to use logisim but the debian version is different from the version who was demonstrated.
We mentionned the presence of many new useful item during the demo.
After a few researchs, i've first found this retirement notice from the original author :
http://www.cburch.com/logisim/retire-note.html (its lates published rev is the debian's one)
and doing further searches, i've found forks and derivates, especially this one :
https://github.com/lawrancej/logisim
which looks very active and followed.
I suggest to use this last uri as new upstream for this package in order to provide the best educational tool for teaching electronics
Regard
