gEDA-user: PCB Autorouter is awesome.

I just routed a small thru-hole board in less than 1 minute.

After putting my footprints where I thought they should go, I sequenced 
  through several of the "optimized routed tracks" routines.  I used the 
following in the following order:

debumpify
unjaggy
miter

I now have a board that is better routed than any I could have done 
manually.

It is totally mindblowing!
