+
+=head1 SYNOPSIS
+
+B<dh_installxfonts> [S<I<debhelper options>>]
+
+=head1 DESCRIPTION
+
+dh_installxfonts is a debhelper program that is responsible for
+registering X fonts, so their corresponding fonts.dir, fonts.alias,
+and fonts.scale be rebuilt properly at install time.
+
+Before calling this program, you should have installed any X fonts provided
+by your package into the appropriate location in the package build
+directory, and if you have fonts.alias or fonts.scale files, you should
+install them into the correct location under etc/X11/fonts in your package
+build directory.
+
+Your package should should depend on xutils (>= 4.0.3) so that the
+update-fonts-* commands are available. (This program adds that dependency to
+${misc:Depends}.)
+
+This program automatically generates the postinst and postrm commands needed
+to register X fonts.  See L<dh_installdeb(1)> for an explanation of how this
+works.
+
+=head1 NOTES
+
+See L<update-fonts-alias(8)>, L<update-fonts-scale(8)>, and
+L<update-fonts-dir(8)> for more information about X font installation.
+
+See Debian policy, section 12.8.5. for details about doing fonts the Debian
+way.
