Usage: program [-:OPTION,OPTION...] ...
The -: flag sets options for the Gambit runtime system. OPTION is one of:
  min-heap=SIZE      set minimum heap size, shorthand: mSIZE
  max-heap=SIZE      set maximum heap size, shorthand: hSIZE
                     the heap SIZE may end with G, M or K (default)
  live-ratio=RATIO   set heap live ratio after GC in percent, shorthand: lRATIO
  parallelism=LEVEL  set parallelism level, shorthand: pLEVEL, where LEVEL can
                     be positive (nb of processors), negative (nb of unused
                     processors), or end with % (ratio of available processors)
  gambit             set Gambit mode, shorthand: S (default mode)
  r5rs               set R5RS mode, shorthand: s
  r7rs               set R7RS mode
  debug[=[OPT...]]   set debugging options, shorthand: d[OPT...], OPT is one of
                      p|a       treat uncaught exceptions as errors
                                (primordial-thread only|all threads)
                      r|s|q     error handling (create a new REPL|start in
                                single-step mode|quit with error status)
                      R|D|Q     user interrupt handling (create a new REPL|
                                defer handling|quit with error status)
                      0..9      verbosity level
                      c         use console as REPL interaction channel
                      -         use stdin/out as REPL interaction channel
                      +         use stdin/out/err as REPL interaction channel
                      @[HOST][:PORT]
                                open connection to HOST:PORT for each thread
                                needing a REPL interaction channel
                                (defaults to 127.0.0.1:44556)
                      $[INTF][:PORT]
                                start a REPL server accepting incoming
                                connections on INTF:PORT
                                (defaults to 127.0.0.1:44555)
  ~~NAME=DIR         override Gambit installation directory ~~NAME where NAME
                     can be the special "bin" and "lib", or empty, or any id
  search=[DIR]       add directory to module search order (or reset it)
  whitelist=[SOURCE] add source to module auto-install whitelist (or reset it)
  ask-install=WHEN   when an uninstalled module is not on the whitelist, ask
                     user if it should be installed, where WHEN is one of

                      never     never ask
                      repl      only if a REPL is running (default)
