Subject: [PATCH] Remove AutoLoader, which we don't use, and all the
 associated gunk. Remove reference to @ISA. Add constant
 definitions for error-codes and event-types. Fill in
 PerlDoc documentation.

 =head1 NAME
 
-Net::Z3950::ZOOM - Perl extension for blah blah blah
+Net::Z3950::ZOOM - Perl extension for invoking the ZOOM-C API.
 
 =head1 SYNOPSIS
 
-  use Net::Z3950::ZOOM;
-  blah blah blah
+ use Net::Z3950::ZOOM;
+ $conn = Net::Z3950::ZOOM::connection_new($host, $port);
+ $errcode = Net::Z3950::ZOOM::connection_error($conn, $errmsg, $addinfo);
+ Net::Z3950::ZOOM::connection_option_set($conn, databaseName => "foo");
+ # etc.
 
 =head1 DESCRIPTION
 
-Stub documentation for Net::Z3950::ZOOM, created by h2xs. It looks like the
-author of the extension was negligent enough to leave the stub
-unedited.
-
-Blah blah blah.
+This module provides a simple thin-layer through to the ZOOM-C
+functions in the YAZ toolkit for Z39.50 and SRW/U communication.  You
+should not be using this very nasty, low-level API.  You should be
+using the C<ZOOM> module instead, which implements a nice, Perlish API
+on top of this module, conformant to the ZOOM Abstract API described at
+http://zoom.z3950.org/api/
 
+To enforce the don't-use-this-module prohibition, I am not even going
+to document it.  If you really, really, really want to use it, then it
+pretty much follows the API described in the ZOOM-C documentation at
+http://www.indexdata.dk/yaz/doc/zoom.tkl
