+
+=head1 SYNOPSIS
+
+B<dh_installxaw> [S<I<debhelper options>>] [B<-n>]
+
+=head1 DESCRIPTION
+
+Warning: The xaw-wrappers package has been removed from debian, and so this
+program is deprecated, and due to be removed soon.
+
+dh_installxaw is a debhelper program that is responsible for installing
+xaw wrappers config files into package build directories.
+
+It also automatically generates the postinst, prerm, and postrm commands
+needed to interface with the debian xaw-wrappers package. See
+L<dh_installdeb(1)> for an explanation of how this works.
+
+If a file named debian/package.xaw exists, then it is installed into
+usr/lib/xaw-wrappers/config/package in the package build directory.
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-n>, B<--noscripts>
+
+Do not modify postinst/prerm/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.
