Default & supported service manager in Wheezy

[Mihamina Rakotomandimby <mihamina.rakotomandimby@rktmb.org>]

Hi all,

A long time ago, when I was young ;-), services used to be managed with 
"invoke-rc.d" & "update-rc.d" on Debian.

Know playing with several distributions, some use "service", "sysctl", 
"systemctl", and some of them are mentionned for managing services in 
Debian.

Typically, on a Debian when I "a2ensite", there is a message indicating 
to "service apache2 reload" in order to fullfill the new VirtualHost 
consideration.

I would like to stick with the "native" tools for each distribution I 
manage: On Wheezy what is the right one? What is wrapping what?

Thank you.
