E.g.,# /bin/sh will be rewritten to /nix/store/<hash>-some-bash/bin/sh.# /usr/bin/env gets special treatment so that ".../bin/env python" is# rewritten to /nix/store/<hash>/bin/python. Interpreters that are# already in the store are left untouched.# A script file must be marked as executable, otherwise it will not be# considered.
