=head1 NAME
dh_installwm - register a window manager
=cut

use Debian::Debhelper::Dh_Lib;
=head1 SYNOPSIS
B<dh_installwm> [S<I<debhelper options>>] [B<-n>] [B<--priority=>I<n>] [S<I<wm> ...>]
=head1 DESCRIPTION
B<dh_installwm> is a debhelper program that is responsible for
generating the F<postinst> and F<prerm> commands that register a window manager
with L<update-alternatives(8)>. The window manager's man page is also
registered as a slave symlink (in v6 mode and up), if it is found in
F<usr/share/man/man1/> in the package build directory.
=head1 FILES
=over 4
=item debian/I<package>.wm
List window manager programs to register.
=back
=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 F<postinst>/F<prerm> scripts. Turns this command into a no-op.
=item I<wm> ...
Window manager programs to register.
=back
=head1 NOTES
Note that this command is not idempotent. L<dh_prep(1)> should be called
between invocations of this command. Otherwise, it may cause multiple
instances of the same text to be added to maintainer scripts.
