# @BLURB: common ebuild functions for multi-abi waf-based packages
# @DESCRIPTION:
# The waf-utils-multilib eclass contains functions that make creating ebuild for
# waf-based packages much easier, while supporting multi-abi installation, for example
# using the ABI_X86 USE_EXPAND variable.
# Its main features are support of common portage default settings.
