=head1 NAME
dh_installxfonts - register X fonts
=cut
use strict;
use warnings;
use Debian::Debhelper::Dh_Lib;
=head1 SYNOPSIS
B<dh_installxfonts> [S<I<debhelper options>>]
=head1 DESCRIPTION
B<dh_installxfonts> is a debhelper program that is responsible for
registering X fonts, so their corresponding F<fonts.dir>, F<fonts.alias>,
and F<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 F<fonts.alias> or F<fonts.scale> files, you should
install them into the correct location under F<etc/X11/fonts> in your
package build directory.
Your package should depend on B<xfonts-utils> so that the
B<update-fonts->I<*> commands are available. (This program adds that dependency to
B<${misc:Depends}>.)
This program automatically generates the F<postinst> and F<postrm> commands needed
to register X fonts. These commands are inserted into the maintainer
scripts by B<dh_installdeb>. 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 11.8.5. for details about doing fonts the Debian
way.
