man apt-get:
[...]
upgrade
upgrade is used to install the newest versions of all packages
currently installed on the system from the sources enumerated in
/etc/apt/sources.list. Packages currently installed with new
versions available are retrieved and upgraded; under no circum-
stances are currently installed packages removed, or packages
not already installed retrieved and installed. New versions of
currently installed packages that cannot be upgraded without
changing the install status of another package will be left at
their current version. An update must be performed first so that
apt-get knows that new versions of packages are
available.
[...]
dist-upgrade
dist-upgrade, in addition to performing the function of upgrade,
also intelligently handles changing dependencies with new ver-
sions of packages; apt-get has a "smart" conflict resolution
system, and it will attempt to upgrade the most important pack-
ages at the expense of less important ones if necessary. The
/etc/apt/sources.list file contains a list of locations from
which to retrieve desired package files.

I use it sometimes...

I do too. And with -u. And it holds back packages on some apt-get
upgrade things without asking me..
