  22 #        guile-tools [OPTION] PROGRAM [ARGS]
  23 #
  24 # PROGRAM is run w/ ARGS.  To see a list of available programs, use
  25 # "guile-tools --help" to find the default scripts directory and then
  26 # do a "ls" on that directory.  Or just read the source 14 lines below.
  27 #
  28 # Options (only one of which may be used at a time):
  29 # --scriptsdir DIR      -- Look in DIR for scripts
  30 # --guileversion VERS   -- Look in $pkgdatadir/VERS/scripts for scripts
  31 #
  32 # TODO
  33 # - handle pre-install invocation
  34 # - "full" option processing (but see comment below)
