# Maintainer: Alexandre Demers <alexandre.f.demers@gmail.com>
# Careful when upgrading this package! It usually breaks ABI without bumping
# soname. Also, be very mindful of the version of spirv-tools that this links
# to. Upstream actually expects the use of the particular commits of
# spirv-tools and spirv-headers that are provided in known_good.json. However,
# if we went that route, we'd have to vendor the resulting spirv-tools libs
# from this glslang build and they would be incompatible with system libs,
# resulting in us having to ship both. Instead, I recommend just waiting until
# upstream releases a compatible version of spirv-tools, then updating the
# spriv-tools system package and only then building glslang against that.
