+=head1 NAME
+
+rrdlist - List directories and rrd databases.
+
+=head1 SYNOPSIS
+
+B<rrdtool> B<list>
+S<[B<--daemon>|B<-d> I<address>]>
+I<path>
+
+=head1 DESCRIPTION
+
+The B<list> function connects to L<rrdcached>, the RRD caching daemon,
+and issues a "list" command for the given path. This provides an 'ls-like'
+interface for traversing and listing the rrd database tree.
+
+=over 8
+
+=item I<path>
+
+The path (starting with '/') with '/' being the rrdcached base_dir.
+
+=item B<--daemon>|B<-d> I<address>
+
+Address of the L<rrdcached> daemon. If not specified, the
+RRDCACHED_ADDRESS environment variable must be set (see below).  For a
+list of accepted formats, see the B<-l> option in the L<rrdcached>
+manual.

+=head1 ENVIRONMENT VARIABLES
+
+The following environment variables may be used to change the behavior of
+C<rrdtoolE<nbsp>list>:
+
+=over 4
+
+=item B<RRDCACHED_ADDRESS>
+
+If this environment variable is set it will have the same effect as specifying
+the C<--daemon> option on the command line. If both are present, the command
+line argument takes precedence.
