Downloading and Installing SabreDAV

Once downloaded, extract it and move the contents of lib to the /var/www/dav/include directory. You should then have the following files present:

* /var/www/include/Sabre
* /var/www/include/Sabre.autoload.php
* /var/www/include/Sabre.includes.php

To load the SabreDAV library, we simple need to include the Sabre.autoload.php file. This will register a new auto-loader in PHP that will load required classes on demand.
Note: If your application already uses its own auto-loader then you may instead want to include the Sabre.includes.php file instead to load every file. If your auto-loader uses PEAR class-naming, then that will also work (e.g. Foo/Bar/Baz.php corresponds to Foo_Bar_Baz) and you don't need to load any SabreDAV files ahead of time.
