Help (this screen):
       --help (-h short option)
              Displays this help; an additional argument (see above) will tell
              emerge to display detailed help.

Actions:
       --clean
              Cleans the system by removing outdated packages which will not
              remove functionalities or prevent your system from working.
              The arguments can be in several different formats :
              * world 
              * system or
              * 'dependency specification' (in single quotes is best.)
              Here are a few examples of the dependency specification format:
              binutils matches
                  binutils-2.11.90.0.7 and binutils-2.11.92.0.12.3-r1
              sys-devel/binutils matches
                  binutils-2.11.90.0.7 and binutils-2.11.92.0.12.3-r1
              >sys-devel/binutils-2.11.90.0.7 matches
                  binutils-2.11.92.0.12.3-r1
              >=sys-devel/binutils-2.11.90.0.7 matches
                  binutils-2.11.90.0.7 and binutils-2.11.92.0.12.3-r1
              <=sys-devel/binutils-2.11.92.0.12.3-r1 matches
                  binutils-2.11.90.0.7 and binutils-2.11.92.0.12.3-r1

       --config
              Runs package-specific operations that must be executed after an
              emerge process has completed.  This usually entails configuration
              file setup or other similar setups that the user may wish to run.

       --depclean (-c short option)
              Cleans the system by removing packages that are not
              associated with explicitly merged packages. Depclean works by
              creating the full dependency tree from the @world set, then
              comparing it to installed packages. Packages installed, but
              not part of the dependency tree, will be uninstalled by
              depclean. See --with-bdeps for behavior with respect to build
              time dependencies that are not strictly required. Packages
              that are part of the world set will always be kept. They can
              be manually added to this set with emerge --noreplace <atom>.
              As a safety measure, depclean will not remove any packages
              unless *all* required dependencies have been resolved. As a
              consequence, it is often necessary to run emerge --update
              --newuse --deep @world prior to depclean.

              WARNING: Inexperienced users are advised to use --pretend
              with this option in order to see a preview of which packages
              will be uninstalled. Always study the list of packages to be
              cleaned for any obvious mistakes. Note that packages listed
              in package.provided (see portage(5)) may be removed by
              depclean, even if they are part of the world set. Also note
              that depclean may break link level dependencies. Thus, it is
              recommended to use a tool such as revdep-rebuild(1) in order
              to detect such breakage.

              Depclean serves as a dependency aware version of --unmerge.
              When given one or more atoms, it will unmerge matched
              packages that have no reverse dependencies. Use --depclean
              together with --verbose to show reverse dependencies.

       --deselect [ y | n ]
              Remove atoms and/or sets from the world file. This action is
              implied by uninstall actions, including --depclean, --prune
              and --unmerge. Use --deselect=n in order to prevent uninstall
              actions from removing atoms from the world file.

       --ignore-default-opts
              Causes EMERGE_DEFAULT_OPTS (see make.conf(5)) to be ignored.

       --info
              Displays important portage variables that will be exported to
              ebuild.sh when performing merges. This information is useful
              for bug reports and verification of settings. All settings in
              make.{conf,globals,defaults} and the environment show up if
              run with the '--verbose' flag.

       --list-sets
              Displays a list of available package sets.

       --metadata
              Transfers metadata cache from ${PORTDIR}/metadata/cache/ to
              /var/cache/edb/dep/ as is normally done on the tail end of an
              rsync update using emerge --sync. This process populates the
              cache database that portage uses for pre-parsed lookups of
              package data.  It does not populate cache for the overlays
              listed in PORTDIR_OVERLAY.  In order to generate cache for
              overlays, use --regen.

       --prune (-P short option)
              WARNING: This action can remove important packages!
              Removes all but the highest installed version of a package
              from your system. Use --prune together with --verbose to show
              reverse dependencies or with --nodeps to ignore all
              dependencies.

       --regen
              Causes portage to check and update the dependency cache of all
              ebuilds in the portage tree. This is not recommended for rsync
              users as rsync updates the cache using server-side caches.
              Rsync users should simply 'emerge --sync' to regenerate.
              In order to specify parallel --regen behavior, use the
              ---jobs and --load-average options. If you would like to
              generate and distribute cache for use by others, use
              egencache(1).

       --resume (-r short option)
              Resumes the most recent merge list that has been aborted due to an
              error. Please note that this operation will only return an error
              on failure. If there is nothing for portage to do, then portage
              will exit with a message and a success condition. A resume list
              will persist until it has been completed in entirety or until
              another aborted merge list replaces it. The resume history is
              capable of storing two merge lists. After one resume list
              completes, it is possible to invoke --resume once again in order
              to resume an older list.

       --search (-s short option)
              Searches for matches of the supplied string in the current local
              portage tree. By default emerge uses a case-insensitive simple 
              search, but you can enable a regular expression search by 
              prefixing the search string with %.
              Prepending the expression with a '@' will cause the category to
              be included in the search.
              A few examples:
              emerge --search libc
                  list all packages that contain libc in their name
              emerge --search '%^kde'
                  list all packages starting with kde
              emerge --search '%gcc$'
                  list all packages ending with gcc
              emerge --search '%@^dev-java.*jdk'
                  list all available Java JDKs

       --searchdesc (-S short option)
              Matches the search string against the description field as well
              the package's name. Take caution as the descriptions are also
              matched as regular expressions.
                emerge -S html
                emerge -S applet
                emerge -S 'perl.*module'

       --sync
              This updates the portage tree that is located in the
              directory that the PORTDIR variable refers to (default
              location is /usr/portage). The SYNC variable specifies the
              remote URI from which files will be synchronized. The
              PORTAGE_SYNC_STALE variable configures warnings that are
              shown when emerge --sync has not been executed recently.

              WARNING:
              The emerge --sync action will modify and/or delete files
              located inside the directory that the PORTDIR variable refers
              to (default location is /usr/portage). For more information,
              see the PORTDIR documentation in the make.conf(5) man page.

              NOTE:
              The emerge-webrsync program will download the entire portage
              tree as a tarball, which is much faster than emerge --sync
              for first time syncs.

       --unmerge (-C short option)
              WARNING: This action can remove important packages!
              Removes all matching packages. This does no checking of
              dependencies, so it may remove packages necessary for the proper
              operation of your system. Its arguments can be atoms or
              ebuilds. For a dependency aware version of --unmerge, use
              --depclean or --prune.

       --version (-V short option)
              Displays the currently installed version of portage along with
              other information useful for quick reference on a system. See
              emerge info for more advanced information.

Options:
       --accept-properties=ACCEPT_PROPERTIES
              This option temporarily overrides the ACCEPT_PROPERTIES
              variable. The ACCEPT_PROPERTIES variable is incremental,
              which means that the specified setting is appended to the
              existing value from your configuration. The special -* token
              can be used to discard the existing configuration value and
              start fresh. See the MASKED PACKAGES section and make.conf(5)
              for more information about ACCEPT_PROPERTIES. A typical usage
              example for this option would be to use --accept-
              properties=-interactive to temporarily mask interactive
              packages. With default configuration, this would result in an
              effective ACCEPT_PROPERTIES value of "* -interactive".

       --alphabetical
              When displaying USE and other flag output, combines the enabled
              and disabled flags into a single list and sorts it alphabetically.
              With this option, output such as USE="dar -bar -foo" will instead
              be displayed as USE="-bar dar -foo"

       --ask [ y | n ] (-a short option)
              Before performing the action, display what will take place
              (server info for --sync, --pretend output for merge, and so
              forth), then ask whether to proceed with the action or abort.
              Using --ask is more efficient than using --pretend and then
              executing the same command without --pretend, as dependencies
              will only need to be calculated once. WARNING: If the "Enter"
              key is pressed at the prompt (with no other input), it is
              interpreted as acceptance of the first choice.  Note that the
              input buffer is not cleared prior to the prompt, so an
              accidental press of the "Enter" key at any time prior to the
              prompt will be interpreted as a choice! Use the --ask-enter-
              invalid option if you want a single "Enter" key press to be
              interpreted as invalid input.

        --ask-enter-invalid
              When used together with the --ask option, interpret a single
              "Enter" key press as invalid input. This helps prevent
              accidental acceptance of the first choice. This option is
              intended to be set in the make.conf(5) EMERGE_DEFAULT_OPTS
              variable.

       --autounmask [ y | n ]
              Automatically unmask packages and generate package.use
              settings as necessary to satisfy dependencies. This option is
              enabled by default. If any configuration changes are
              required, then they will be displayed after the merge list
              and emerge will immediately abort. If the displayed
              configuration changes are satisfactory, you should copy and
              paste them into the specified configuration file(s), or
              enable the --autounmask-write option. The EMERGE_DEFAULT_OPTS
              variable may be used to disable this option by default in
              make.conf(5).

       --autounmask-write [ y | n ]
              If --autounmask is enabled, changes are written to config
              files, respecting CONFIG_PROTECT and --ask.

       --backtrack COUNT
              Specifies an integer number of times to backtrack if
              dependency calculation fails due to a conflict or an
              unsatisfied dependency (default: '10').

       --binpkg-respect-use [ y | n ]
              Tells emerge to ignore binary packages if their use flags
              don't match the current configuration. (default: 'n')

       --buildpkg [ y | n ] (-b short option)
              Tells emerge to build binary packages for all ebuilds
              processed in addition to actually merging the packages.
              Useful for maintainers or if you administrate multiple Gentoo
              Linux systems (build once, emerge tbz2s everywhere) as well
              as disaster recovery. The package will be created in the
              ${PKGDIR}/All directory. An alternative for already-merged
              packages is to use quickpkg(1) which creates a tbz2 from the
              live filesystem.

       --buildpkgonly (-B short option)
              Creates a binary package, but does not merge it to the
              system. This has the restriction that unsatisfied dependencies
              must not exist for the desired package as they cannot be used if
              they do not exist on the system.

       --changed-use
              This is an alias for --reinstall=changed-use.

       --changelog (-l short option)
              When pretending, also display the ChangeLog entries for packages
              that will be upgraded.

       --color < y | n >
              Enable or disable color output. This option will override NOCOLOR
              (see make.conf(5)) and may also be used to force color output when
              stdout is not a tty (by default, color is disabled unless stdout
              is a tty).

       --columns
              Display the pretend output in a tabular form. Versions are
              aligned vertically.

       --complete-graph [ y | n ]
              This causes emerge to consider the deep dependencies of all
              packages from the world set. With this option enabled, emerge
              will bail out if it determines that the given operation will
              break any dependencies of the packages that have been added
              to the graph. Like the --deep option, the --complete-graph
              option will significantly increase the time taken for
              dependency calculations. Note that, unlike the --deep option,
              the --complete-graph option does not cause any more packages
              to be updated than would have otherwise been updated with the
              option disabled. Using --with-bdeps=y together with
              --complete-graph makes the graph as complete as possible.

       --config-root=DIR
              Set the PORTAGE_CONFIGROOT environment variable which is
              documented in the emerge(1) man page.

       --debug (-d short option)
              Tell emerge to run the ebuild command in --debug mode. In this
              mode, the bash build environment will run with the -x option,
              causing it to output verbose debug information print to stdout.
              --debug is great for finding bash syntax errors as providing
              very verbose information about the dependency and build process.

       --deep [DEPTH] (-D short option)
              This flag forces emerge to consider the entire dependency tree of
              packages, instead of checking only the immediate dependencies of
              the packages. As an example, this catches updates in libraries
              that are not directly listed in the dependencies of a package.
              Also see --with-bdeps for behavior with respect to build time
              dependencies that are not strictly required.

       --emptytree (-e short option)
              Reinstalls target atoms and their entire deep dependency
              tree, as though no packages are currently installed. You
              should run this with --pretend first to make sure the result
              is what you expect.

       --exclude ATOMS
              A space separated list of package names or slot atoms. Emerge
              won't  install any ebuild or binary package that matches any
              of the given package atoms.

       --fail-clean [ y | n ]
              Clean up temporary files after a build failure. This is
              particularly useful if you have PORTAGE_TMPDIR on tmpfs. If
              this option is enabled, you probably also want to enable
              PORT_LOGDIR (see make.conf(5)) in order to save the build
              log.

       --fetchonly (-f short option)
              Instead of doing any package building, just perform fetches for
              all packages (main package as well as all dependencies.) When
              used in combination with --pretend all the SRC_URIs will be
              displayed multiple mirrors per line, one line per file.

       --fetch-all-uri (-F short option)
              Same as --fetchonly except that all package files, including those
              not required to build the package, will be processed.

       --getbinpkg [ y | n ] (-g short option)
              Using the server and location defined in PORTAGE_BINHOST, portage
              will download the information from each binary file there and it
              will use that information to help build the dependency list. This
              option implies '-k'. (Use -gK for binary-only merging.)

       --getbinpkgonly [ y | n ] (-G short option)
              This option is identical to -g, as above, except it will not use
              ANY information from the local machine. All binaries will be
              downloaded from the remote server without consulting packages
              existing in the packages directory.

       --jobs [JOBS] (-j short option)
              Specifies the number of packages to build simultaneously. If
              this option is given without an argument, emerge will not
              limit the number of jobs that can run simultaneously. Also
              see the related --load-average option. Note that interactive
              packages currently force a setting of --jobs=1. This issue
              can be temporarily avoided by specifying --accept-
              properties=-interactive.

       --keep-going [ y | n ]
              Continue as much as possible after an error. When an error
              occurs, dependencies are recalculated for remaining packages
              and any with unsatisfied dependencies are automatically
              dropped. Also see the related --skipfirst option.

       --load-average LOAD
              Specifies that no new builds should be started if there are
              other builds running and the load average is at least LOAD (a
              floating-point number). This option is recommended for use in
              combination with --jobs in order to avoid excess load. See
              make(1) for information about analogous options that should
              be configured via MAKEOPTS in make.conf(5).

       --misspell-suggestions < y | n >
              Enable or disable misspell suggestions. By default, emerge
              will show a list of packages with similar names when a
              package doesn't exist. The EMERGE_DEFAULT_OPTS variable may
              be used to disable this option by default

       --newuse (-N short option)
              Tells emerge to include installed packages where USE flags
              have changed since compilation. This option also implies the
              --selective option. If you would like to skip rebuilds for
              which disabled flags have been added to or removed from IUSE,
              see the related --reinstall=changed-use option.

       --noconfmem
              Portage keeps track of files that have been placed into
              CONFIG_PROTECT directories, and normally it will not merge the
              same file more than once, as that would become annoying. This
              can lead to problems when the user wants the file in the case
              of accidental deletion. With this option, files will always be
              merged to the live fs instead of silently dropped.

       --nodeps (-O short option)
              Merge specified packages, but don't merge any dependencies.
              Note that the build may fail if deps aren't satisfied.

       --noreplace (-n short option)
              Skip the packages specified on the command-line that have
              already been installed.  Without this option, any packages,
              ebuilds, or deps you specify on the command-line *will* cause
              Portage to remerge the package, even if it is already installed.
              Note that Portage won't remerge dependencies by default.
              Also note that this option takes precedence over options such
              as --newuse, preventing a package from being reinstalled even
              though the corresponding USE flag settings may have changed.

       --nospinner
              Disables the spinner regardless of terminal type.

       --usepkg-exclude ATOMS
              A space separated list of package names or slot atoms. Emerge
              will ignore matching binary packages.

       --rebuild-exclude ATOMS
              A space separated list of package names or slot atoms. Emerge
              will not rebuild matching packages due to --rebuild.

       --rebuild-ignore ATOMS
              A space separated list of package names or slot atoms. Emerge
              will not rebuild packages that depend on matching  packages
              due to --rebuild.

       --oneshot (-1 short option)
              Emerge as normal, but don't add packages to the world profile.
              This package will only be updated if it is depended upon by
              another package.

       --onlydeps (-o short option)
              Only merge (or pretend to merge) the dependencies of the
              specified packages, not the packages themselves.

       --package-moves [ y | n ]
              Perform package moves when necessary. This option is enabled
              by default. WARNING: This option should remain enabled under
              normal circumstances. Do not disable it unless you know what
              you are doing.

       --pretend (-p short option)
              Instead of actually performing the merge, simply display what
              ebuilds and tbz2s *would* have been installed if --pretend
              weren't used.  Using --pretend is strongly recommended before
              installing an unfamiliar package.  In the printout, N = new,
              U = updating, R = replacing, F = fetch  restricted, B = blocked
              by an already installed package, D = possible downgrading,
              S = slotted install. --verbose causes affecting use flags to be
              printed out accompanied by a '+' for enabled and a '-' for
              disabled USE flags.

       --quiet [ y | n ] (-q short option)
              Effects vary, but the general outcome is a reduced or condensed
              output from portage's displays.

       --quiet-build [ y | n ]
              Redirect all build output to logs alone, and do not display
              it on stdout.

       --quiet-unmerge-warn
              Disable the warning message that's shown prior to --unmerge
              actions. This option is intended to be set in the
              make.conf(5) EMERGE_DEFAULT_OPTS variable.

       --rebuild-if-new-rev [ y | n ]
              Rebuild packages when dependencies that are used at both
              build-time and run-time are built, if the dependency is not
              already installed with the same version and revision.

       --rebuild-if-new-ver [ y | n ]
              Rebuild packages when dependencies that are used at both
              build-time and run-time are built, if the dependency is not
              already installed with the same version. Revision numbers are
              ignored.

       --rebuild-if-unbuilt [ y | n ]
              Rebuild packages when dependencies that are used at both
              build-time and run-time are built.

       --rebuilt-binaries [ y | n ]
              Replace installed packages with binary packages that have
              been rebuilt. Rebuilds are detected by comparison of
              BUILD_TIME package metadata. This option is enabled
              automatically when using binary packages (--usepkgonly or
              --getbinpkgonly) together with --update and --deep.

       --rebuilt-binaries-timestamp=TIMESTAMP
              This option modifies emerge's behaviour only if --rebuilt-
              binaries is given. Only binaries that have a BUILD_TIME that
              is larger than the given TIMESTAMP and that is larger than
              that of the installed package will be considered by the
              rebuilt-binaries logic.

       --reinstall changed-use
              Tells emerge to include installed packages where USE flags have
              changed since installation.  Unlike --newuse, this option does
              not trigger reinstallation when flags that the user has not
              enabled are added or removed.

       --reinstall-atoms ATOMS
              A space separated list of package names or slot atoms. Emerge
              will treat matching packages as if they are not installed,
              and reinstall them if necessary.

       --root=DIR
              Set the ROOT environment variable which is documented in the
              emerge(1) man page.

       --root-deps[=rdeps]
              If no argument is given then build-time dependencies of
              packages for ROOT are installed to ROOT instead of /. If the
              rdeps argument is given then discard all build-time
              dependencies of packages for ROOT. This option is only
              meaningful when used together with ROOT and it should not be
              enabled under normal circumstances. For currently supported
              EAPI values, the build-time dependencies are specified in the
              DEPEND variable. However, behavior may change for new EAPIs
              when related extensions are added in the future.

       --select [ y | n ]
              Add specified packages to the world set (inverse of
              --oneshot). This is useful if you want to use
              EMERGE_DEFAULT_OPTS to make --oneshot behavior default.

       --selective [ y | n ]
              This is similar to the --noreplace option, except that it
              does not take precedence over options such as --newuse. Some
              options, such as --update, imply --selective. Use
              --selective=n if you want to forcefully disable --selective,
              regardless of options like --update.

       --skipfirst
              This option is only valid when used with --resume.  It
              removes the first package in the resume list. Dependencies
              are recalculated for remaining packages and any that have
              unsatisfied dependencies or are masked will be automatically
              dropped. Also see the related --keep-going option.

       --tree (-t short option)
              Shows the dependency tree using indentation for dependencies.
              The packages are also listed in reverse merge order so that
              a package's dependencies follow the package. Only really useful
              in combination with --emptytree, --update or --deep.

       --unordered-display
              By default the displayed merge list is sorted using the order
              in which the packages will be merged. When --tree is used
              together with this option, this constraint is removed,
              hopefully leading to a more readable dependency tree.

       --update (-u short option)
              Updates packages to the best version available, which may not
              always be the  highest version number due to masking for
              testing and development. Package atoms specified on the
              command line are greedy, meaning that unspecific atoms may
              match multiple versions of slotted packages.

       --use-ebuild-visibility [ y | n ]
              Use unbuilt ebuild metadata for visibility checks on built
              packages.

       --useoldpkg-atoms ATOMS
              A space separated list of package names or slot atoms. Emerge
              will prefer matching binary packages over newer unbuilt
              packages.

       --usepkg [ y | n ] (-k short option)
              Tell emerge to use binary packages (from $PKGDIR) if they are
              available, thus possibly avoiding some time-consuming compiles.
              This option is useful for CD installs; you can export
              PKGDIR=/mnt/cdrom/packages and then use this option to have
              emerge "pull" binary packages from the CD in order to satisfy
              dependencies.

       --usepkgonly [ y | n ] (-K short option)
              Like --usepkg above, except this only allows the use of binary
              packages, and it will abort the emerge if the package is not
              available at the time of dependency calculation.

       --verbose (-v short option)
              Effects vary, but the general outcome is an increased or expanded
              display of content in portage's displays.

       --with-bdeps < y | n >
              In dependency calculations, pull in build time dependencies that
              are not strictly required. This defaults to 'n' for installation
              actions and 'y' for the --depclean action. This setting can be
              added to EMERGE_DEFAULT_OPTS (see make.conf(5)) and later
              overridden via the command line.
