Welcome to Brian's Lisps!
All AutoLISP programs are custom built by Brian Forbes. Once written, they will immediately become open source and will be available for public download. Brian has also written a book. You can preview it here: From Noah to Hercules (What History Says About Early Man).
You can help this site grow by uploading your AutoLISP Routines to this site. Those will be made available for free for anyone to download.
