This GLEP is an official specification of the syntax of the keyword.

Keywords will consist out of two parts separated by a hyphen ('-'). The -left hand part of the keyword 2-tuple is the architecture, such as -ppc64, sparc and x86. The right hand part indicates the operating -system or distribution, such as linux, macos, darwin, obsd, etc. If the +part up to the first hyphen from the left of the keyword 2-tuple is the +architecture, such as ppc64, sparc and x86.

The variables ELIBC, KERNEL and ARCH are currently set in the profiles when other than their defaults for a GNU/Linux system. They can as such easily be overridden and defined by the user. To @@ -290,7 +298,7 @@
