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