+=head1 NAME
+
+xpath - a script to query XPath statements in XML documents.
+
+=head1 SYNOPSIS
+
+B<xpath [-s suffix] [-p prefix] [-q] -e query [-e query] ... [file] ...>
+
+=head1 DESCRIPTION
+
+B<xpath> uses the L<XML::XPath|XML::XPath> perl module to make XPath queries
+to any XML document. The L<XML::XPath|XML::XPath> module aims to comply exactly
+to the XPath specification at C<http://www.w3.org/TR/xpath> and yet
+allows extensions to be added in the form of functions.
+
+The script takes any number of XPath pointers and tries to apply them
+to each XML document given on the command line. If no file arguments
+are given, the query is done using C<STDIN> as an XML document.
+
+When multiple queries exist, the result of the last query is used as
+context for the next query and only the result of the last one is output.
+The context of the first query is always the root of the current document.
+
+=head1 OPTIONS
+
+=head2 B<-q>
+
+Be quiet. Output only errors (and no separator) on stderr.
+
+=head2 B<-s suffix>
+
+Place C<suffix> at the end of each entry. Default is a linefeed.
+
+=head2 B<-p prefix>
+
+Place C<prefix> preceding each entry. Default is nothing.
