search [options] <substring>: Search for a package Options: -r <feedname>: Only search in this feed
uninstall -a|<package>: Uninstall a package Options: -a : Uninstalls all packages.
update -a|<feedname(s)>: Update packages and lists of feeds in feeds.conf . Options: -a : Update all feeds listed within feeds.conf.

V=99 and V=1 are now deprecated in favor of a new verbosity class system, though the old flags are still supported. You can set the V variable on the command line (or OPENWRT_VERBOSE in the environment) to one or more of the following characters:
- s: stdout+stderr (equal to the old V=99) - c: commands (for build systems that suppress commands by default, e.g. kbuild, cmake) - w: warnings/errors only (equal to the old V=1)
make package/example/download - download the soures of example make package/example/prepare - extract the sources, apply patches and download if necessary make package/example/compile - compile example, prepare and download if necessary make package/example/clean - clean the sourcecode make package/index - build a repository index to make the output directory usable as local opkg source
