Hi Alan K, !

I take your point!  Better then nothing, I suppose.  I like your "area * 
complexity" algorithm. But I think they've been using this for what, 6+ 
years now?  Must work for them.

I'm getting the hang of the library, I made two parts (PIC18F2520 and 
MAX232) by copying parts and making the changes I wanted.  Nice!  One 
more part to copy/paste, and I'll have all the power straightened out. 
I seem to recall an "alias" function, must be for a different program.

A Yahoo list for Eagle would be nice!
