# This eclass contains the default phase functions for packages which
# use the meson build system.

# @EXAMPLE:
# Typical ebuild using meson.eclass:
#
# @CODE
# EAPI=6
#
# inherit meson
#
# ...
#
# src_configure() {
# local emesonargs=(
# -Dqt4=$(usex qt4 true false)
# -Dthreads=$(usex threads true false)
# -Dtiff=$(usex tiff true false)
# )
# meson_src_configure
# }
#
# ...

# @CODE
