IMPORTANT NOTICE

Beginning with version 2.6.0, the WU-FTPD Development Group is moving the build process to

use GNU Autoconf. Until this move is completed, both build systems will remain supported.

You are encouraged to use the new "configure" command to select options, then "make" to

compile the daemon. For details on this, read the README.AUTOCONF file. If problems occur,

please report them to the development group via email to wuftpd-members@wu-ftpd.org We are

soliciting feedback on the new configuration process, and your help is greatly appreciated.
If you choose to continue to use the original build process, bear in mind it will be phased

out over the next few releases: when we are reasonably sure the new configuration system

works for most target platforms.

Sleeping for five seconds, sorry for the interruption.
