quse - find pkgs using useflags

quse [opts] <useflag>

quse searches in ebuilds for a match in IUSE or LICENSE. It can also search for US-flags and show their descriptions.

-e, --exact: Search for exact string, e.g. do not use regular expression matching.
-a, --all: List all ebuilds, don't match anything.
-L, --license: Use the LICENSE vs IUSE.
-D, --describe: Describe the USE flag, when no US-flag given and combined with -p, lists all US-flags with their descriptions (and enabled state prefixed with an asterisk when used with -I) per package.
-I, --installed: Only search installed packages.
-p <arg>, --package <arg>: Restrict matching to package or category.
-R, --repo: Show repository the ebuild originates from.
-F <arg>, --format <arg>: Print matched atom using given format string.
--root <arg>: Set the ROOT env var.
-v, --verbose: Show versions for packages that match the search. Also shows problems encountered during parsing. These are mostly diagnostic and indicate possible incorrectness in the results.
-q, --quiet: Ignored for compatibility with other qapplets.
-C, --nocolor: Don't output color.
--color: Force color in output.
-h, --help: Print this help and exit.
-V, --version: Print version and exit.
