+
+=head1 SYNOPSIS
+
+  use OpenSSL::Util::Pod;
+
+  my %podinfo = extract_pod_info("foo.pod");
+
+  # or if the file is already opened...  Note that this consumes the
+  # remainder of the file.

+
+=item B<extract_pod_info GLOB, HASHREF>
+
+=item B<extract_pod_info GLOB>
+
+Extracts information from a .pod file, given a STRING (file name) or a
+GLOB (a file handle).  The result is given back as a hash table.
+
+The additional hash is for extra parameters:
+
+=over
+
+=item B<section =E<gt> N>
+
+The value MUST be a number, and will be the man section number
+to be used with the given .pod file.
+
+=item B<debug =E<gt> 0|1>
+
+If set to 1, extra debug text will be printed on STDERR

+
+=over
+
+=item B<extract_pod_info> returns a hash table with the following
+items:
+
+=over
+
+=item B<section =E<gt> N>
+
+The man section number this .pod file belongs to.  Often the same as
+was given as input.
+
+=item B<names =E<gt> [ "name", ... ]>
+
+All the names extracted from the NAME section.
