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