  Notes:
    Only one option can be used at a time.
    For install and remove options, a capitalized -I or -R will remove --ask.
    Long options are available for all options, look at the script.
  Post-update part 1, kernel building:

    make oldconfig && make menuconfig                 # convert oldconf, newopts
    make dep ; make clean ; make && make modules_install

    eclean-kernel -n 2                       # keep two newest kernels
  Post-update part 2, other details:
    emerge --depclean
    revdep-rebuild                           # (i.e. "${0##*/}" -i:v)
    perl-cleaner --all && python-updater     # if py/perl updtd & not total updt
