Gentoolkit とは何ですか？
Gentoo is a unique distribution and presents some complexities that simply do not exist for other distributions. As Gentoo developers and contributors discovered some of these complexities, they also wrote tools to help users and administrators work around them. Many tools have been contributed to the Gentoo project and are included in the package.

Gentoolkit contains a whole bunch of useful tools to help users manage packages and keep track of what is going on in their systems. Most users - particularly those who update systems often - will benefit from having Gentoolkit installed.

Emerge
As with most other Gentoo packages, installation is as simple as an :

Finding documentation
Any documentation that a program might have (other than man pages) is stored in.

euse
is a tool to see, set and unset USE flags at various places. For more information on USE flags, please refer to the USE Flags. See for complete help and all options.

Viewing, setting, and unsetting USE flags
The command reads the current active USE flags and displays them.

Similarly the command is used to view active global USE flags. The command does the same for active local USE flags. and  are sub-options to  and need an option before them (like  ) to function correctly.

is able to set or unset USE flags. The commands used for this are (enable a flag) and  (disable a flag).

Enabling a USE flag:

The file looks like so after the command was ran:

Disabling a USE flag:

Again, the file after the command:

revdep-rebuild
This tool is Gentoo's Reverse Dependency rebuilder. It will scan the installed ebuilds to find packages that have become broken as a result of an upgrade of a package they depend on. It can emerge those packages for users automatically but it can also happen that a given package does not work with the currently installed dependencies, in which case you should upgrade the broken package to a more recent version. will pass flags to which lets you use the   flag to see what is going to be emerged again before going any further.

To rebuild some packages run without the   flag and the listed packages will be emerged again.

glsa-check
glsa-check is mainly a test tool that keeps track of the various GLSA's (Gentoo Linux Security Advisory) and will eventually be integrated into and.

eread
is a simple utility to display elog files produced by >=. The saving of elog files can be enabled by setting a couple of variables in :

Once elog has been set up to satisfaction, run to view the log files.

Select a number and the file will be displayed using the paging program specified in the PAGER environment variable. If PAGER is not set, it will use. The PAGER environmental variable can be set using (module  ).

After displaying the elog item, you will be prompted if you want to delete the file.

eclean
is a tool to remove old source files and old binary packages from the system.

When building and installing packages, the source files are downloaded and preserved in DISTDIR, usually. This can accumulate several gigabytes of material over time if it is not cleaned periodically. Users should run to clean source files from DISTDIR.

It is possible to create archives of installed packages by using or. These archived packages are kept in PKGDIR, usually. When they are no longer needed, or if they are too old, can be ran to remove them from PKGDIR. It is a good way to ensure that any binary packages on the system are only the latest versions.
