Sendfile is an asynchronous file transfer service for the Internet, like the
sendfile facility in Bitnet: Any user A can send files to another user B
without B being active in any way.

Sendfile which is an implementation of the SAFT protocol (Simple Asynchronous
File Transfer) offers you a true asynchronous file transfer service for the
Internet. Virtually any form of file can be sent, including encrypted ones.

The sendfile package contains 5 main programs:
sendfiled - the sendfile daemon which will be started by inetd
sendfile - the sendfile client for sending files
sendmsg - the send-message client for sending one-line text messages
receive - the receive client for picking up already received files
fetchfile - the O-SAFT client to obtain files from a remote SAFT server
