Usage help. Provide help for the subject given as an optional argument.
If no argument is provided, curl displays the most important command line arguments.
The argument can either be a category or a command line option. When a
category is provided, curl shows all command line options within the given
category. Specify category all to list all available options.
If category is specified, curl displays all available help categories.
If the provided subject is instead an existing command line option, specified either in its short form with a single dash and a single letter, or in the long form with two dashes and a longer name, curl displays a help text for that option in the terminal.
The help output is extensive for some options.
If the provided command line option is not known, curl says so.
