+ 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 - Powerfull 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
