 extend pfet,pcap *pdiff 280 exclusive "Transistor length < %d (PL.1a)"
 extend nfet,pcap *ndiff 280 exclusive "Transistor length < %d (PL.1a)"   <- maybe should be nfet,ncap
 width pfet,pcap 300 angles "Bent Transistor length < %d (PL.7)"
 width nfet,pcap 300 angles "Bent Transistor length < %d (PL.7)"   <- maybe should be nfet,ncap

 extend mvpfet,mvpcap *mvpdiff 500 exclusive "MV Transistor length < %d (PL.1a)"
 extend mvnfet,mvpcap *mvndiff 600 exclusive "MV Transistor length < %d (PL.1a)"   <- maybe should be mvnfet,mvncap
 width mvpfet,mvpcap 700 angles "Bent MV Transistor length < %d (PL.7)"
 width mvnfet,mvpcap 700 angles "Bent MV Transistor length < %d (PL.7)"   <- maybe should be mvnfet,mvncap

Is this ok?

All valid points, and I will fix them. Thanks!

Fixed in the last push to the repo on opencircuitdesign.com.
