+
+Display information about curl and the libcurl version it uses.
+
+The first line includes the full version of curl, libcurl and other 3rd party
+libraries linked with the executable.
+
+This line may contain one or more TLS libraries. curl can be built to support
+more than one TLS library which then makes curl - at start-up - select which
+particular backend to use for this invocation.
+
+If curl supports more than one TLS library like this, the ones that are *not*
+selected by default are listed within parentheses. Thus, if you do not specify
+which backend to use (with the `CURL_SSL_BACKEND` environment variable) the
+one listed without parentheses is used. Such builds also have `MultiSSL` set as
+a feature.
+
+The second line (starts with `Release-Date:`) shows the release date.
+
+The third line (starts with `Protocols:`) shows all protocols that libcurl
+reports to support.
+
+The fourth line (starts with `Features:`) shows specific features libcurl
+reports to offer. Available features include:
+
+## `alt-svc`
+Support for the Alt-Svc: header is provided.
+
+## `AsynchDNS`
+This curl uses asynchronous name resolves. Asynchronous name resolves can be
+done using either the c-ares or the threaded resolver backends.
+
+## `brotli`
+Support for automatic brotli compression over HTTP(S).
+
+## `CharConv`
+curl was built with support for character set conversions (like EBCDIC)
+
+## `Debug`
+This curl uses a libcurl built with Debug. This enables more error-tracking
+and memory debugging etc. For curl-developers only.
+
+## `ECH`
+ECH support is present.
+
+## `gsasl`
+The built-in SASL authentication includes extensions to support SCRAM because
+libcurl was built with libgsasl.
+
+## `GSS-API`
+GSS-API is supported.
+
+## `HSTS`
+HSTS support is present.
+
+## `HTTP2`

+## `MultiSSL`
+This curl supports multiple TLS backends.
+
+## `NTLM`
