That pulls in dependencies but does not install packages that
would otherwise be forbidden by the priority system.

E.g.: if you have foobar 1.5 in stable and foobar 2.1 in
backports, and they each depend on libfoobar of the same version
number, then

apt-get install foobar=2.1

will fail saying that it requires libfoobar 2.1 but version 1.5
is to be installed.

You can then solve that by saying

apt-get install foobar=2.1 libfoobar=2.1

but many interesting packages will have a web of dependencies,
and sometimes following them will get you to a place it is hard
to escape.

The backports repository is generally safe (or safe-ish) because
the packages in it are meant to work in a mostly-stable system.

Other repos are less accomodating.
