  27 # some of the tests:

  29 # shell functions (do we care?)
  30 # var=${var:-val}
  31 # unset
  32 # set --
  33 # IFS parsing
  34 ## not exiting with -e and failed "if", the way Ultrix does (Ultrix 4.2?)
  35 # "$@" expands to zero arguments if passed zero arguments
  36 # $SHELL -c 'echo $1' bad good
  37 # test -x
  38 # positional parameters greater than 9
  39 # arithmetic expansion $(( ... ))
  40 # getopts
  41

  44 # For example, on HP-UX 9, /bin/posix/sh is the supposedly-compliant shell.
