+=head1 NAME
+
+WebService::Google::Suggest - Google Suggest as an API
+
+=head1 SYNOPSIS
+
+  use WebService::Google::Suggest;
+
+  my $suggest = WebService::Google::Suggest->new();
+  my @suggestions = $suggest->complete("goog");
+  for my $suggestion (@suggestions) {
+      print "$suggestion->{query}: $suggestion->{results} results\n";
+  }
+
+=head1 DESCRIPTION
+
+WebService::Google::Suggest allows you to use Google Suggest as a Web Service API to retrieve completions to your search query or partial query. This module is based on Adam Stiles' hack (http://www.adamstiles.com/adam/2004/12/hacking_google_.html).
+
+=head1 METHODS
+
+=over 4
+
+=item new
+
+  $suggest = WebService::Google::Suggest->new();
+
+Creates new WebService::Google::Suggest object.
+
+=item complete
+
+  @suggestions = $suggest->complete($query);
+
+Sends your C<$query> to Google web server and fetches suggestions for
+the query. Suggestions are in a list of hashrefs, for example with
+query "Google":
+
+  @suggestions = (
+    { query => "google", results => 122000000 },
+    { query => "google toolbar", results => 2620000 },
+    ...
+  );
+
+Note that C<results> value does NOT contain commas and "results" text.
+
+=item ua
+
+  $ua = $suggest->ua;
+
+Returns underlying LWP::UserAgent object. It allows you to change
+User-Agent (Windows IE by default), timeout seconds and various
+properties.
