- switch all invidual files documenting command line options into .md, as the documentation is now markdown-looking. - made the parser treat 4-space indents as quotes - switch to building the curl.1 manpage using the "mainpage.idx" file, which lists the files to include to generate it, instead of using the previous page-footer/headers. Also, those files are now also .md ones, using the same format. I gave them underscore prefixes to make them sort separately: _NAME.md, _SYNOPSIS.md, _DESCRIPTION.md, _URL.md, _GLOBBING.md, _VARIABLES.md, _OUTPUT.md, _PROTOCOLS.md, _PROGRESS.md, _VERSION.md, _OPTIONS.md, _FILES.md, _ENVIRONMENT.md, _PROXYPREFIX.md, _EXITCODES.md, _BUGS.md, _AUTHORS.md, _WWW.md, _SEEALSO.md - updated test cases accordingly Closes #12751

# `--curves`
|
|
|
|
Tells curl to request specific curves to use during SSL session establishment
|
|
according to RFC 8422, 5.1. Multiple algorithms can be provided by separating
|
|
them with `:` (e.g. `X25519:P-521`). The parameter is available identically in
|
|
the OpenSSL `s_client` and `s_server` utilities.
|
|
|
|
--curves allows a OpenSSL powered curl to make SSL-connections with exactly
|
|
the (EC) curve requested by the client, avoiding nontransparent client/server
|
|
negotiations.
|
|
|
|
If this option is set, the default curves list built into OpenSSL are ignored.
