-Opal
-====
-
-Opal is a Gemini server written in Rust. It is meant to serve dynamic content
-through CGI and does not serve static files. In a way, it is a companion project
-to the [Agate][agate] Gemini server which only serves static files. The
-project's goals are:
-
-- Focus on a small set of features (around CGI) but do them correctly.
-- Be nice with old/stupid hardware (TLS 1.2 is OK, be efficient, etc).
-- Don't add features unless someone actively wants them in.
-- Try to keep resources (binary size, memory, etc) under tight control.
-
-Opal uses the `openssl` Rust bindings, which work with OpenSSL and LibreSSL, so
-it should work properly on those platforms. I currently only support Linux
-systems but if there is interest in other platforms let's do this together!
-
-Opal is licensed as GPLv3.

-Usage
------
-
-Use `opal -h` to get a list of options. There is no config file, every setting
-can be configured from the command line.
-
-- `-a, --address <address>`: specify the address to listen to.
-- `-c, --cert <cert>`: server certificate path.
-- `-k, --key <key>`: server private key path.
-- `-r, --root-path <root_path>`: path to CGI scripts root.
-- `-e, --env <key=value>`: additional environment variables for CGI scripts;
-    this option can be used multiple times.

-CGI support
------------
-
-Opal tries to implement [RFC 3875][rfc3875] (CGI 1.1) and provides all the
-required environment variables to processes. It also add a bunch of Gemini
-specific variables, like a lot of other servers (Gemserv, Gmid, Gmnisrv, …). The
-environment for the subprocess is cleaned and should only contain those
-variables.

-
-Opal does not provide `CONTENT_LENGTH`, `CONTENT_TYPE`, `REMOTE_IDENT` because
-they do not make much sense in Gemini. `PATH_TRANSLATED` is also not implemented
-by pure laziness.
-
-The `TLS_CLIENT_HASH` is a string that starts with "SHA256:" followed by the
-SHA256 digest of the DER representation of the client certificate, as an
-uppercase hex-string.
-
-It can be a bit confusing which variable represent what data, especially those
-related to the URL and the path. Take the following request as example:
-`gemini://localhost/env/sub1/sub2?search=élément`. Suppose our CGI root, in
-`/cgi`, contains the executable script named `env`. The variables will be:
-
-```
-GEMINI_DOCUMENT_ROOT=/cgi
-GEMINI_SCRIPT_FILENAME=/cgi/env
-GEMINI_URL=gemini://localhost/env/sub1/sub2?search=%C3%A9l%C3%A9ment
-GEMINI_URL_PATH=/env/sub1/sub2
-SCRIPT_NAME=/env
-PATH_INFO=/sub1/sub2
-QUERY_STRING=search=%C3%A9l%C3%A9ment
-```

-Roadmap
--------
-
-Things to consider:
-
-- Multiple listening addresses, at least so we can easily listen on both IPv4
-    and IPv6.
-- Support SCGI; a bit more complex but should save resources on smol hardware.
-
-Things that probably won't be considered:
-
-- Serve static files; so many other servers to that correctly already!
-- Any kind of security mechanism that is not properly motivated.
-- FastCGI; come on…
