+dh_installinit - install init scripts into package build directories
+
+=cut
+
+use strict;
use Debian::Debhelper::Dh_Lib;
+
+=head1 SYNOPSIS
+
+B<dh_installinit> [S<I<debhelper options>>] [B<--name=>I<name>] [B<-n>] [B<-R>] [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.
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-n>, B<--noscripts>
+
+Do not modify postinst/postrm/prerm scripts.
+
+=item B<-o>, B<--onlyscripts>
+
+Only modify postinst/postrm/prerm scripts, do not actually install any init
+script or default files. May be useful if the init script is shipped and/or
+installed by upstream in a way that doesn't make it easy to let
+dh_installinit find it.
+
+=item B<-R>, B<--restart-after-upgrade>
+
+Do not stop the init script until after the package upgrade has been
+completed. This is different than the default behavior, which stops the
+script in the prerm, and starts it again in the postinst.
+
+This can be useful for daemons that should not have a possibly long
+downtime during upgrade. But you should make sure that the daemon will not
+get confused by the package being upgraded while it's running before using
+this option.
+
+=item B<-r>, B<--no-restart-on-upgrade>
+
+Do not stop init script on upgrade.
+
+=item B<--no-start>
+
+Do not start the init script on install or upgrade, or stop it on removal.
+Only call update-rc.d. Useful for rcS scripts.
+
+=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<--name=>I<name>
+
+Install the init script (and default file) using the filename I<name>
+instead of the default filename, which is the package name. When this
+parameter is used, dh_installinit looks for and installs files named
+debian/package.name.init and debian/package.name.default, instead of the
+usual debian/package.init and debian/package.default.
+
+=item B<--init-script=>I<scriptname>
+
+Use "scriptname" as 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). 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 parameter is deprecated, use the --name parameter instead.
+
+=item B<--error-handler=>I<function>
+
+Call the named shell function if running the init script fails. The
+function should be provided in the prerm and postinst scripts, before the
+#DEBHELPER# token.
+
+=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.
