+=head1 NAME
+
+dh_scrollkeeper - generate ScrollKeeper registration scripts
+
+=cut
+
+use strict;
+use Debian::Debhelper::Dh_Lib;
+
+=head1 SYNOPSIS
+
+B<dh_scrollkeeper> [S<I<debhelper options>>] [B<-n>] [S<I<directory>>]
+
+=head1 DESCRIPTION
+
+B<dh_scrollkeeper> is a debhelper program that handles correctly
+registering OMF files that it finds in package build trees with
+ScrollKeeper.
+
+This command automatically adds maintainer script snippets for registering
+and unregistering files with ScrollKeeper (unless B<-n> is used). A
+dependency on scrollkeeper will be added to C<${misc:Depends}>, so be sure
+your package uses that variable in F<debian/control>. See
+L<dh_installdeb(1)> for an explantion of Debhelper maintainer script
+snippets.
+
+It will also change any DTD declarations in the OMF and DocBook files
+to refer to local files instead of remote URLs. This change does not
+modify the source files, but the files in the package build tree.
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-n>, B<--noscripts>
+
+Do not modify F<postinst>/F<postrm> scripts.
+

+
+=head1 NOTES
+
+Note that this command is not idempotent. "dh_clean -k" should be
+called between invocations of this command. Otherwise, it may cause
+multiple instances of the same text to be added to maintainer scripts.
