# The default compiled in settings are fairly paranoid.

Turn on the below options to have the server actually do ASCII# mangling on files when in ASCII mode.# Beware that on some FTP servers, ASCII support allows a denial of service# attack (DoS) via the command "SIZE / big/file" in ASCII mode.

This is disabled by# default to avoid remote users being able to cause excessive I/O on large# sites.
