Name : proftpd
Product : Fedora 33
Version : 1.3.7c
Release : 1.fc33
URL :   http://www.proftpd.org/
Summary : Flexible, stable and highly-configurable FTP server
Description :
ProFTPD is an enhanced FTP server with a focus toward simplicity, security,
and ease of configuration. It features a very Apache-like configuration
syntax, and a highly customizable server infrastructure, including support for
multiple 'virtual' FTP servers, anonymous FTP, and permission-based directory
visibility.

This package defaults to the standalone behavior of ProFTPD, but all the
needed scripts to have it run by systemd instead are included.
