ACCEPT KEYWORDS/ko

The  variable informs the package manager which ebuilds' KEYWORDS values it is allowed to accept.

Where the variable is set?
The variable is usually set through the Gentoo profile but can be overruled in the users' file, per-package in the  file/directory or even on the command line.

Stable and unstable keywords
The default value of most profiles'  variable is the architecture itself, like   or. In these cases, the package manager will only accept ebuilds whose KEYWORDS variable contains this architecture. If the user wants to be able to install and work with ebuilds that are not considered production-ready yet, they can add the same architecture but with the  prefix to it, like so:

는 증분 변수이므로 이 변수에 시험 버전 키워드를 붙일때 안정 버전 키워드를 지정하면 안됩니다.

If the setting is not to be made system-wide, then it can be set per-package in the file or directory:

In addition to the normal values from   supports three special tokens :
 * — package is visible if it is stable on any architecture
 * — package is visible if it is in testing on any architecture
 * — package is always visible ( are ignored completely)

The last choice is useful for live package versions (which are svn/git/mercurial/… versions of packages, supported through what is called a live ebuild and which don't have a  variable).
