ftp is a Networking Library that provides FTP client protocol support to Common Lisp programs. (Slightly modified from Matthew Danish's original System cl-ftp.)

For a version of the edited version that uses usocket instead of acl-compat, check out cl-ftp on bknr.net

Note (2009.04.09): I've incorporated the usocket conversion into the 1.5.0 release of cl-ftp (thanks Hans!). That said, The acl-compat version is still available for those who would prefer it. --pinterface
