The way formatting of argp `--help' output may be controlled to
some extent by a program's users, by setting the ARGP_HELP_FMT
environment variable to a comma-separated list (whitespace is ignored)
of the following tokens:
- `dup-args'
-
- `no-dup-args'
-
Turn duplicate-argument-mode on or off. In duplicate argument
mode, if an option which accepts an argument has multiple names, the
argument is shown for each name; otherwise, it is only shown for the
first long option, and a note is emitted later so the user knows that it
applies to the other names as well. The default is `no-dup-args',
which is less consistent, but prettier.
- `dup-args-note'
-
- `no-dup-args-note'
-
Enable or disable the note informing the user of suppressed option
argument duplication. The default is `dup-args-note'.
- `short-opt-col=n'
-
Show the first short option in column n (default 2).
- `long-opt-col=n'
-
Show the first long option in column n (default 6).
- `doc-opt-col=n'
-
Show `documentation options' (see section Flags for Argp Options) in column
n (default 2).
- `opt-doc-col=n'
-
Show the documentation for options starting in column n (default 29).
- `header-col=n'
-
Indent group headers (which document groups of options) to column
n (default 1).
- `usage-indent=n'
-
Indent continuation lines in `Usage:' messages to column n
(default 12).
- `rmargin=n'
-
Word wrap help output at or before column n (default 79).
