+
+
+; This file is processed by the script opts.sh.  It is a database of
+; command line options, with each record separated by a blank line,
+; and each field appearing on its own line.  The first field is the
+; command-line switch with the leading "-" removed.  All options
+; beginning with "f" or "W" are implicitly assumed to take a "no-"
+; form; this form should not be listed.  If you do not want this
+; negative form and you want it to be automatically rejected, add
+; RejectNegative to the second field.
+
+; The second field is a space-separated list of which parts of the
+; compiler recognize the switch, as declared by "Language" entries.
+; If the switch takes an argument, then you should also specify
+; "Joined" and/or "Separate" to indicate where the argument can
+; appear.  If a Joined argument can legitimately be omitted, specify
+; "JoinedOrMissing" instead of "Joined".  If the argument to a switch
+; is a non-negative integer, you can specify "UInteger" and the switch
+; decoder will convert the argument for you, or complain to the user
+; if the argument is invalid.
+
+; The third field is the help text to output with --help.  This is
+; automatically line-wrapped on output.  Normally the switch is output
+; automatically, with the help text on the right hand side of the
+; output.  However, if the help text contains a tab character, the
+; text to the left of the tab is output instead of the switch, and the
+; text to its right forms the help.  This is useful for elaborating on
+; what type of argument a switch takes, for example.  If the second
+; field contains "Undocumented" then nothing is output with --help.
+; Only do this with good reason like the switch being internal between
+; the driver and the front end - it is not an excuse to leave a switch
+; undocumented.
+
+; Comments can appear on their own line anwhere in the file, preceded
+; by a semicolon.  Whitespace is permitted before the semicolon.
+
+; For each switch XXX below, an enumeration constant is created by the
+; script opts.sh spelt OPT_XXX, but with all non-alphanumeric
+; characters replaced with an underscore.
+
+; Please try to keep this file in ASCII collating order.
