${NO}Displays packages that are installed but which none

system, but are not currently installed.
${BR}USAGE:
${BL}${PROG}${YL} [${NO}options${YL}]${NO}
${BL}${PROG}${GR} --help${NO}
${BR}OPTIONS:
${GR}-U, --unneeded${NO} display unneeded packages that are installed (${GR}green${NO})
${GR}-N, --needed${NO} display needed packages that are not installed (${RD}red${NO})
${GR}-R, --removed${NO} display installed packages not in portage (${YL}yellow${NO})
${GR}-I, --interactive${NO} interactively modify world file before proceeding
${GR}-C, --nocolor${NO} output without color, if necessary, package types are
noted with ${GR}U, N${NO} and ${GR}R${NO} respectively
${GR}-v, --verbose${NO} be more verbose
${GR}-q, --quiet${NO} be quiet (just output the packages, no extra info)
${BR}NOTES:
${GR}*${NO} If this script is run on a system that is not up-to-date or which hasn't
been cleaned (with '${BL}emerge -c${NO}') recently, the output may be deceptive.
${GR}*${NO} If the same package name appears in all three categories, then it is
definitely time to update that package and then run '${BL}emerge -c${NO}'.
${GR}*${NO} The ${GR}-U, -N${NO} and ${GR}-R${NO} options may be combined, defaults to ${GR}-UNR${NO}"
