+# `ruby-local-exec` is a drop-in replacement for the standard Ruby
+# shebang line:
+#
+#    #!/usr/bin/env ruby-local-exec
+#
+# Use it for scripts inside a project with an `.rbenv-version`
+# file. When you run the scripts, they'll use the project-specified
+# Ruby version, regardless of what directory they're run from. Useful
+# for e.g. running project tasks in cron scripts without needing to
+# `cd` into the project first.
