1# This setup hook, for each output, moves everything in $output/lib64
2# to $output/lib, and replaces $output/lib64 with a symlink to
3# $output/lib. The rationale is that lib64 directories are unnecessary
4# in Nix (since 32-bit and 64-bit builds of a package are in different
5# store paths anyway).
6# If the move would overwrite anything, it should fail on rmdir.
