NAME
dh_installwm - register a window manager
SYNOPSIS
dh_installwm [debhelper options] [-n] [--priority=n] [wm ...]
DESCRIPTION
dh_installwm is a debhelper program that is responsible for generating
the postinst and postrm 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), if it is found in
usr/share/man/man1/ in the package build directory.
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.
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, --noscripts
Do not modify postinst/postrm scripts. Turns this command into a
no-op.
wm ...
The commands used to run the window manager or window managers you
want 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.
