 Apache2::Authen::Passphrase is a perl module which provides easy-to-use Apache2 authentication. It exports some utility functions and it contains a PerlAuthenHandler.
 
+The password hashes are stored in YAML files in an directory (called the C<rootdir>), one file per user.
+
+Set the C<rootdir> like this:
+
+  $Apache2::Authen::Passphrase::rootdir = '/path/to/rootdir';
+
+or by setting the C<AAP_ROOTDIR> enviroment variable to the desired value.
