Default options

• --usepkg=y

  tells emerge to use binary packages (from $PKGDIR) if they are available

• --binpkg-changed-deps=y

  Tells emerge to ignore binary packages for which the corresponding ebuild dependencies have changed since the packages were built

• --binpkg-respect-use=y

  Tells emerge to ignore binary packages if their USE flags don't match the current configuration.

• --quiet=y

  Results may vary, but the general outcome is a reduced or condensed output from portage's displays

• --verbose=y

  Currently this flag causes emerge to print out GNU info errors, if any, and to show the USE flags that will be used for each package when pretending

• --keep-going=y

  Continue as much as possible after an error. See also --resume and --skipfirst

• --jobs=${NPROC} --load-average=${NPROC}

  emerge runs NPROC jobs at a time and try to keep the load average of the system less than ${NPROC}
