 158 Package Manipulation:
 159         update                  Update list of available packages
 160         upgrade                 Upgrade all installed packages to latest version
 161         install <pkg>           Download and install <pkg> (and dependencies)
 162         install <file.ipk>      Install package <file.ipk>
 163         install <file.deb>      Install package <file.deb>
 164         remove <pkg>            Remove package <pkg>
 165
 166 Informational Commands:
 167         list                    List available packages and descriptions
 168         files <pkg>             List all files belonging to <pkg>
 169         search <file>           Search for a packaging providing <file>
 170         info [pkg [<field>]]    Display all/some info fields for <pkg> or all
 171         status [pkg [<field>]]  Display all/some status fields for <pkg> or all
 172         depends <pkg>           Print uninstalled package dependencies for <pkg>
 173
 174 Options:
 175         -d <dest_name>          Use <dest_name> as the the root directory for
 176         -dest <dest_name>       package installation, removal, upgrading.
 177                                 <dest_name> should be a defined dest name from the
 178                                 configuration file, (but can also be a directory
 179                                 name in a pinch).
 180         -o <offline_root>       Use <offline_root> as the root for offline installation.
 181         -offline <offline_root>
 182
 183 Force Options (use when ipkg is too smart for its own good):
 184         -force-depends          Make dependency checks warnings instead of errors
 185         -force-defaults         Use default options for questions asked by ipkg.
 186                                 (no prompts). Note that this will not prevent
 187                                 package installation scripts from prompting.
