+=head1 SYNOPSIS
+
+B<dh_installinit> [S<I<debhelper options>>] [B<--init-script=>I<scriptname>] [B<-n>] [B<-r>] [B<-d>] [S<B<--> I<params>>]
+
+=head1 DESCRIPTION
+
+dh_installinit is a debhelper program that is responsible for installing
+init scripts and associated defaults files into package build directories.
+
+It also automatically generates the postinst and postrm and prerm commands
+needed to set up the symlinks in /etc/rc*.d/ and to start and stop the init
+scripts.
+
+If a file named debian/package.init exists, then it is installed into
+etc/init.d/package in the package build directory, with "package" replaced
+by the package name.
+
+If a file named debian/package.default exists, then it is installed into
+etc/default/package in the package build directory, with "package" replaced
+by the package name.
+
+Historically this program generates postrm and prerm commands that run the
+init scripts by hand. In V4 mode, it uses the invoke-rc.d program instead.
+See L<debhelper(1)> for details about V4 mode. If you decide to use this, you
+should make your package depend on sysvinit (>= 2.80-1) (this dependency is
+added to ${misc:Depends} by this program in V4 mode).
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-n>, B<--noscripts>
+
+Do not modify postinst/postrm/prerm scripts.
+
+=item B<-r>, B<--no-restart-on-upgrade>
+
+Do not restart daemon on upgrade.
+
+=item B<-d>, B<--remove-d>
+
+Remove trailing "d" from the name of the package, and use the result for the
+filename the init script is installed as in etc/init.d/ , and the default file
+is installed as in etc/default/ . This may be useful for daemons with names
+ending in "d". (Note: this takes precedence over the --init-script parameter
+described below.)
+
+=item B<-u>I<params> B<--update-rcd-params=>I<params>
+
+=item B<--> I<params>
+
+Pass "params" to L<update-rc.d(8)>. If not specified, "defaults" will be
+passed to L<update-rc.d(8)>.
+
+=item B<--init-script=>I<scriptname>
+
+Use "scriptname" as for the filename the init script is installed as in
+etc/init.d/ (and also use it as the filename for the defaults file, if it
+is installed). This is useful if you need to have an init script with a name
+different from the package's name. Note that if you use this parameter,
+dh_installinit will look to see if a file in the debian/ directory exists
+that looks like "package.scriptname" and if so will install it as the init
+script in preference to the files it normally installs. This feature is really
+only useful if you need a single package to install more than one init script.
+

+
+=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.
