The s-expression one, because its PRETTY, thanks to Wayne.

Use the source, the recursive descent parsing is not that hard to follow, since at each
level you have the set of choices possible.
You can also use the python script I posted a 4 days ago to convert a number of standard
libraries to the new format into a scratch dir so you have a large sampling of existing
Use the latest source code so you pick up the *.Cu support. Another way is to export a
footprint from the library editor, export now uses the new format.

This also can occur if I replace an mCU by an almost-compatible mCU (if a net named "button1" net is connected to RA0 on a pic18F4550, if I replace the pic18f4550 by a pic18f2550 which has less pin, there is no problem, but other pins disappear)

Conflict seems most prevalent these days, and I have no answers for that.
