apt-get upgrade vs apt-get dist-upgrade

[T <mlist4suntong@yahoo.com>]

Hi,

where can I find the difference between apt-get upgrade and apt-get
dist-upgrade?

I have always been using apt-get upgrade, but according to
http://www.debian-administration.org/articles/43
it is not correct:

| apt-get upgrade is not correct, it is only recommended for the stable
| distribution. If you're using testing or unstable do apt-get -du
| dist-upgrade or dselect-upgrade. Read the fabulous manual if you wonder why.

So where can I find the fabulous manual?

Manual page of apt:
