apt-get - Cover for dpkg
This is an allout cover for dpkg implementing a safer front end. It is
based largely on libapt-pkg.
The syntax is different,
apt-get [opt] command [things]
Where command is:
update - Resyncronize the package files from their sources
upgrade - Smart-Download the newest versions of all packages
dselect-upgrade - Follows dselect's changes to the Status: field
and installes new and removes old packages
dist-upgrade - Powerful upgrader designed to handle the issues with
a new distribution.
install - Download and install a given package (by name, not by .deb)
check - Update the package cache and check for broken packages
clean - Erase the .debs downloaded to /var/cache/apt/archives and
the partial dir too
