-# @DESCRIPTION:

-# 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() {

-#	multibuild_foreach_variant python_compile
-# }

-# @DESCRIPTION:
-# The current variant which the function was executed for.
-#
-# If nested multibuilds are used, this value can be an array. In that

-

-# @DESCRIPTION:
-# The unique identifier for a multibuild run. In a simple run, it is

-# contains the complete selection tree.
-#
-# It can be used to create variant-unique directories and files.
-#
-# 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
-# amd64-double
-# @CODE
-
-# @ECLASS-VARIABLE: BUILD_DIR
-# @DESCRIPTION:
-# The current build directory. In global scope, it is supposed
-# to contain an 'initial' build directory. If unset, ${S} is used.
-#
-# multibuild_foreach_variant() sets BUILD_DIR locally
-# to variant-specific build directories based on the initial value
-# of BUILD_DIR.
-#
-# 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
-# ${WORKDIR}/foo-1.3-python2_6
