"Introduction Every version of the FTP specification has added a few new commands@ with the early ones summarized in RFC 959 [RFC0959]. RFC 2389 [RFC2389] established a mechanism for specifying and negotiating extensions to the FTP protocol specified in RFC 959@ by means of ""FEAT Strings"" identifying extensions supported by the FTP server@ and sent in response to a ""FEAT"" command. The number of extensions continues to grow@ not all of them supported by FEAT. An IANA registry is established to reduce the likelihood of a conflict of names and the consequent ambiguity and to encourage the sharing of information. This specification establishes that registry."
