 About
 =====
 
 Python FTP server library provides a high-level portable interface to easily
 write very efficient, scalable and asynchronous FTP servers with Python. It is
-the most complete `RFC-959 <https://datatracker.ietf.org/doc/html/rfc959.html>`__ FTP server
-implementation available for `Python <https://www.python.org/>`__ programming
-language.

 - Uses **sendfile(2)** (see `pysendfile <https://github.com/giampaolo/pysendfile>`__)
   system call for uploads (Linux only).
-- Uses epoll() / kqueue() / select() to handle concurrency asynchronously.
-- ...But can optionally skip to a
-  `multiple thread / process <https://pyftpdlib.readthedocs.io/en/latest/tutorial.html#changing-the-concurrency-model>`__
-  model (as in: you'll be free to block or use slow filesystems).
