 SYNOPSIS
         use Parse::ACNS;
-        my $parser = Parse::ACNS->new(
-            version => 'compat',
-        );

+        my $data = Parse::ACNS->new->parse( XML::LibXML->load_xml( string => $xml ) );
 
 DESCRIPTION
+    ACNS stands for Automated Copyright Notice System. It's an open source,
+    royalty free system that universities, ISP's, or anyone that handles
+    large volumes of copyright notices can implement on their network to
+    increase the efficiency and reduce the costs of responding to the
+    notices... See "http://mpto.unistudios.com/xml/" for more details.
+
+    This module parses ACNS XML into a perl data structure. Supports both
+    0.6 and 0.7 version. Parser strictly follows XML Schemas, so throws
+    errors on malformed data.
+
+    However, it doesn't extract ACNS XML from email messages.
+
+METHODS
+  new
+    Constructor, takes list of named arguments.
+

+
+        compat - default value, can parse both 0.7 and 0.6 XML by making

+        only difference between the spec versions.

+
+    Takes XML::LibXML::Document containing an ACNS XML and returns it as a
+    perl struture. Read XML::LibXML::Parser on parsing from different
+    sources.
