versatile, virtual-hosting FTP daemon

ProFTPd is a powerful replacement for wu-ftpd. This File Transfer Protocol
daemon supports hidden directories, virtual hosts, and per-directory
".ftpaccess" files. It uses a single main configuration file, with a
syntax similar to Apache.

Because of the advanced design, anonymous-FTP directories can have
an arbitrary internal structure (bin, lib, etc, and special files are
not needed). Advanced features such as multiple password files and
upload/download ratios are also supported.

This is a convenience transitional package used to install all provided
modules, so you can safely remove it after upgrading. You should
alternatively install proftpd-basic and one or more of the other
proftpd-mod-* packages if you need advanced features.
