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-" | |
c83857ff NB |
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. | |
fef3106c NB |
30 | |
31 | ; The second field is a space-separated list of which parts of the | |
be43ab4e NB |
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 | |
7b086b11 NB |
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. | |

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 | |
f2ac9964 NB |
47 | ; what type of argument a switch takes, for example. If the second |
48 | ; field contains "Undocumented" then nothing is output with --help. | |
49 | ; Only do this with good reason like the switch being internal between | |
50 | ; the driver and the front end - it is not an excuse to leave a switch | |
51 | ; undocumented. | |
