This is the Courier authentication library. 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.

Additional information can be found in the INSTALL file.
The authentication API is documented.
