Hi, Aaron Swartz here. Project Gutenberg is about putting up text versions of out-of-copyright books. This project is about creating a catalog of _every_ book, with links to PG, scans, Amazon.com, PDFs, print on demand, etc. -- anything we can get our hands on. Gutenberg books are in our catalog, of course, but so are millions more.
BSD insists on putting ``ports'' under/usr/local, while Linux insists on not using/usr/local for anything that comes with the system. Both approaches produce failures for the users: programs not starting, for example. More importantly, the lack of cross-platform compatibility imposes tremendous costs on the UNIX community.
