There is a lot in the "Alice source" package - including a CMU specific mathematical package (which looks very nice, but basically is undocumented). In addition, there seems to be a mixed use of the Java swing package and some other (probably earlier generation) graphics tools - which is also hard to decipher.
Personally, I can't figure it out at all.

hi DrJim,
sorry, i can't understand your reply very well, you means there are packages in Alice source code, however, why can't i compile it.
i got many error reports in eclipse when i tried to do that.
i reviewed everybody's reply, aikmin said the code is complete open, i'm confused, if the code is open, we could learn form it and compile it, but some people can't do that like me.
i'm not good at JAVA, so if i said something wrong, please forgive me, i alway think all members in Alice design are great persons, they gave all children a great gift, my nephew is very interest in Alice, i learn Alice for him.
