The bug
entry.sh resolves its own directory with readlink -f "$0". BSD/macOS readlink does not implement -f, so the command exits under set -e before judges update starts. The repository documentation only requires Ruby/Bundler and does not declare GNU coreutils as a prerequisite.
Reproduction
On macOS (or another BSD userland), run ./entry.sh job /tmp/job with judges installed. The shell reports readlink: illegal option -- f and exits.
Expected
The entry point should resolve its directory portably (or document and enforce the GNU coreutils dependency) so the documented command works on supported Unix systems.
