Debian branches and when a packet is moved from testing to stable

[Arnau Rebassa i Villalonga <arnau.rebassa@androme.es>]

Hi all,

  I've been searching some info about the different Debian's branches 
and the policy followed to move one package from SID->testing->stable 
but I haven't found this info. I guess it's explained somewhere in the 
Debian's site but I couldn't found it, any hint? ;)

Cheers!!
