# USE=blas doesn't make much sense. Most meshing algorithms won't work without
# a working blas/lapack implementation, so we remove the USE flag.
# USE=python needs ENABLE_PRIVATE_API which is currently discouraged by upstream
# as it enables experimental developer stuff, therefore numpy can also not
# be used.
# USE=zipper currently fails to compile
