=head1 NAME
dh_installwm - register a window manager
=cut
use strict;
use Debian::Debhelper::Dh_Lib;
=head1 SYNOPSIS
dh_installwm [debhelper options] [-n] [--priority=n] [wm ...]
=head1 DESCRIPTION
dh_installwm is a debhelper program that is responsible for
generating the postinst and postrm commands that register a window manager
with L<update-alternatives(8)>
Any window manager programs specified as parameters will be registered in
the first package dh_installwm is told to act on. By default, this is the
first binary package in debian/control, but if you use -p, -i, or -a flags,
it will be the first package specified by those flags.
Files named debian/package.wm can list other window manager programs to
register.
=head1 OPTIONS
=over 4
=item B<--priority=>I<n>
Set the priority of the window manager. Default is 20, which is too low for
most window managers; see the Debian Policy document for instructions on
calculating the correct value.
=item B<-n>, B<--noscripts>
Do not modify postinst/postrm scripts. Turns this command into a no-op.
=item I<wm ...>
The commands used to run the window manager or window managers you want to
register.
=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.
