# ocamlc has several mechanisms for linking a bytecode image to the runtime
# which executes it. The exact mechanism depends on the platform and the precise
# location of the runtime. The boot compiler (boot/ocamlc) therefore needs this
# additional information, which comes from the stdlib build and is copied into
# boot/ as part of coldstart. See read_runtime_launch_info in
# bytecomp/bytelink.ml for further details.
