+dh_installwm - register a window manager

+=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).  It must be installed in
+F<usr/share/man/man1/> in the package build directory prior to calling
+B<dh_installwm>.  In compat 9 and earlier, the manpage was optional.
+
+=head1 FILES
+
+=over 4
+
+=item debian/I<package>.wm
+
+List window manager programs to register.
+
+Supports substitution variables in compat 13 and later as
+documented in L<debhelper(7)>.

+
+=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<--no-scripts>
+
+Do not modify F<postinst>/F<prerm> scripts. Turns this command into a no-op.
+
+=item B<-A>, B<--all>
+
+Modify scripts for window managers specified by command line
+parameters in ALL packages acted on, not just the first.
+
+=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.
