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