-# @DESCRIPTION:
-# An array specifying all enabled variants which multibuild_foreach*
-# can execute the process for.
-#
-# In ebuild, it can be set in global scope. Eclasses should set it
-# locally in function scope to support nesting properly.
-#
-# Example:
-# @CODE
-# python_foreach_impl() {
-#	local MULTIBUILD_VARIANTS=( python{2_5,2_6,2_7} ... )
-#	multibuild_foreach_variant python_compile
-# }
-# @CODE
-
-# @ECLASS-VARIABLE: MULTIBUILD_VARIANT
-# @DESCRIPTION:
-# The current variant which the function was executed for.
-#
-# If nested multibuilds are used, this value can be an array. In that
-# case, the first element will name the deepest multibuild, and the next
-# elements will go outwards.
-#
-# Example value:
-# @CODE
-# python2_6
-# @CODE
-
-# @ECLASS-VARIABLE: MULTIBUILD_ID
-# @DESCRIPTION:
-# The unique identifier for a multibuild run. In a simple run, it is
-# equal to MULTIBUILD_VARIANT. In a nested multibuild environment, it
-# contains the complete selection tree.
-#
-# It can be used to create variant-unique directories and files.
