# @FUNCTION: waf-utils_waflibdir
# @USAGE: [<waf-binary>]
# @DESCRIPTION:
# Echoes the absolute path to the directory containing waf-based
# project's waflib python module. Ensures that the waflib shipped with a
# project is unpacked if it isn't already. This waflib may be safely
# patched because waf-lite will not touch the waflib directory when it
# is run if it already exists. Uses the waf binary in WAF_BINARY or the
# first argument.
#
# @EXAMPLE
# @CODE
# pushd "$(waf-utils_waflibdir)" || die "Unable to patch waflib"
# epatch "${FILESDIR}"/${P}-waf-fix.patch
# popd
# @CODE
#
# Note that if you are using the python eclass, you must either call
# python_set_active_version or call waf-utils_waflibdir() from within a
# function run by python_execute().
