I have done some cleanup in the libraries.  There is more left to do, 
but at this point, all m4 footprints "work" in the sense that they have 
no m4 or pcb syntax errors.  The usual "no guarantees about mechanical 
accuracy" still apply.  For the above 3 footprint families, I fixed the 
ACYmP and RCYmP to behave exactly like ACYm and RCYm except for having a 
polarity marking in silk screen.  The BREm just seemed like to vague of 
a description to be a useful footprint so I removed them.  One could 
argue tha the ACY and RCY ones should also go, but that will have to be 
a different day.


I have also fixed up a number of hole sizes, but you should still pay 
attention and verify them yourselves.
