Copies of this library code used to exist in other tarballs: Courier,
Courier-IMAP, and SqWebMail. Building and installing any of these packages
would've automatically installed this authentication code.
The authentication library is now a separate, standalone package. This
authentication library must now be installed, separately, before upgrading
to the following builds (or if installing them for the first time):
Courier 0.48, Courier-IMAP 4.0, and SqWebMail 5.0. See NEWS for more information.

This is the FreeBSD Ports Collection. For an easy to use
WEB-based interface to it, please see:
http://www.freebsd.org/ports
For general information on the ports collection, please see the
FreeBSD Handbook which is available from:
file://localhost/usr/share/doc/handbook/handbook.html
(if you installed the doc distribution on your machine)
Or:
http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/
for the latest official version from FreeBSD-current.
The section "The Ports Collection" will tell you how to use the
ports and packages and the "Porting Applications" section
describes how one can contribute to the ports collection.
If you would like to search for a given port, you can do so easily
by saying:
make search key="<keyword>"
Which will generate a list of all ports matching <keyword>.
NOTE: This tree can GROW significantly in size during normal usage!
The distribution tar files can and do accumulate in /usr/ports/distfiles,
and the individual ports will also use up lots of space in their work
subdirectories unless you remember to "make clean" after you're done
building a given port. /usr/ports/distfiles can also be periodically
cleaned without ill-effect, though if you don't have the original
distribution tarball(s) for something on CDROM then you will need to pull
it all over your network connection again if you ever try to build the
associated port.
