dh_installwm

DH_INSTALLWM(1) 						     Debhelper							   DH_INSTALLWM(1)

NAME

       dh_installwm - register a window manager

SYNOPSIS

       dh_installwm [debhelperoptions] [-n] [--priority=n] [wm...]

DESCRIPTION

       dh_installwm is a debhelper program that is responsible for generating the postinst and prerm commands that register a window manager with
       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
       usr/share/man/man1/ in the package build directory prior to calling dh_installwm.  In compat 9 and earlier, the manpage was optional.

FILES

       debian/package.wm
	   List window manager programs to register.

OPTIONS

       --priority=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.

       -n, --no-scripts
	   Do not modify postinst/prerm scripts. Turns this command into a no-op.

       wm ...
	   Window manager programs to register.

NOTES

       Note that this command is not idempotent. 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.

SEE ALSO

       debhelper(7)

       This program is a part of debhelper.
