+   
+   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 installs 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
