The keyword specifies how option works when specified multiple times: - single: the last provided value replaces the earlier ones - append: it supports being provided multiple times - boolean: on/off values - mutex: flag-like option that disable anoter flag The 'gen.pl' script then outputs the proper and unified language for each option's multi-use behavior in the generated man page. The multi: header is requires in each .d file and will cause build error if missing or set to an unknown value. Closes #9759

curl man page generator
This is the curl man page generator. It generates a single nroff man page output from the set of sources files in this directory.
There is one source file for each supported command line option. The output
gets page-header prepended and page-footer appended. The format is
described below.
Option files
Each command line option is described in a file named <long name>.d, where
option name is written without any prefixing dashes. Like the file name for
the -v, --verbose option is named verbose.d.
Each file has a set of meta-data and a body of text.
Meta-data
Added: (version number in which this was added)
Arg: (the argument the option takes)
c: (copyright line)
Example: (example command line, without "curl" and can use `$URL`)
Experimental: yes (if so)
Help: (short text for the --help output for this option)
Long: (long form name, without dashes)
Magic: (description of "magic" options)
Multi: single/append/boolean/mutex (if used more than once)
Mutexed: (space separated list of options this overrides, no dashes)
Protocols: (space separated list for which protocols this option works)
Requires: (space separated list of features this requires, no dashes)
See-also: (space separated list of related options, no dashes)
Short: (single letter, without dash)
SPDX-License-Identifier: curl
Tags: (space separated list)
--- (end of meta-data)
Body
The body of the description. Only refer to options with their long form option
version, like --verbose. The output generator will replace such with the
correct markup that shows both short and long version.
Text written within *asterisks* will get shown using italics. Text within
two **asterisks** will get shown using bold.
Text that is prefixed with a space will be treated like an "example" and will be output in monospace.
Header and footer
page-header is the file that will be output before the generated options
output for the master man page.
page-footer is appended after all the individual options.
Generate
./gen.pl mainpage
This command outputs a single huge nroff file, meant to become curl.1. The
full curl man page.
./gen.pl listhelp
Generates a full curl --help output for all known command line options.
