  22 ; This file is processed by the script opts.sh.  It is a database of
  23 ; command line options, with each record separated by a blank line,
  24 ; and each field appearing on its own line.  The first field is the
  25 ; command-line switch with the leading "-" removed.  All options
  26 ; beginning with "f" or "W" are implicitly assumed to take a "no-"
  27 ; form; this form should not be listed.  If you do not want this
  28 ; negative form and you want it to be automatically rejected, add
  29 ; RejectNegative to the second field.
  30
  31 ; The second field is a space-separated list of which parts of the
  32 ; compiler recognize the switch, as declared by "Language" entries.
  33 ; If the switch takes an argument, then you should also specify
  34 ; "Joined" and/or "Separate" to indicate where the argument can
  35 ; appear.  If a Joined argument can legitimately be omitted, specify
  36 ; "JoinedOrMissing" instead of "Joined".  If the argument to a switch
  37 ; is a non-negative integer, you can specify "UInteger" and the switch
  38 ; decoder will convert the argument for you, or complain to the user
  39 ; if the argument is invalid.
  40
  41 ; The third field is the help text to output with --help.  This is
  42 ; automatically line-wrapped on output.  Normally the switch is output
  43 ; automatically, with the help text on the right hand side of the
  44 ; output.  However, if the help text contains a tab character, the
  45 ; text to the left of the tab is output instead of the switch, and the
  46 ; text to its right forms the help.  This is useful for elaborating on
  47 ; what type of argument a switch takes, for example.
  48
  49 ; Comments can appear on their own line anwhere in the file, preceded
  50 ; by a semicolon.  Whitespace is permitted before the semicolon.
  51
  52 ; For each switch XXX below, an enumeration constant is created by the
  53 ; script opts.sh spelt OPT_XXX, but with all non-alphanumeric
  54 ; characters replaced with an underscore.
  55
  56 ; Please try to keep this file in ASCII collating order.
