-# NOTE: this PKGBUILD is a temporary WIP
-# it is based on the AUR PKGBUILD, which also runs makeicecat at build-time
-# makeicecat requires an active internet connection though, so that code was removed
-# this was introduced hastily, because 'icu' had changed,
-#   and the 78.9.0 parabola PKGBUILD had "sandbox violation" problems at the time
-# eventually, the original parabola PKGBUILD should be restored/merged with this recipe
-#   per rev: 04c332d29f362070a883baa3eab40df4a6f701d3
-# TODO: this PKGBUILD has several issues:
-# - it is adapted only for x86_64
-# - it has branding issues eg: missing "topsites", serach-engines, previous parabola patching
-# - it has two switchable implememtations (per '_make_srcball' - both work);
-#   but preparing the upstream source-ball requires network access,
-#   and the source-ball is only necessary becuase gnuzilla has not published one for v78

-  While SPMD is not the intended use case for `packed_simd`, it is possible to
-  combine the library with [`rayon`][rayon] to poorly emulate [ISPC]'s SPMD programming
