README.md: update project destiny
Promote version to v0.1.1
A library for communication to servers through the Gemini protocol.
NOTE: gemini-request (and the main project retrorocket) has been defunct since November 29, 2020 (Gemini v0.14.3). This project was not meant to be a serious, maintained library, but rather to help in developing Retrorocket to see if the UI toolkit McCLIM is a good match for me.
Project Gemini is a semi-recent internet protocol project that describes itself as somewhere between Gopher and the conventional Web. Instead of being the simplest protocol, Gemini intends to have the highest "oomph" for its weight. If you're unfamiliar with Project Gemini and want to learn more, I recommend reading the de-facto homepage in HTTP or in Gemini (Mozz.us Proxy).
This library could be used for making Gemini-compliant browsers or violated requests. While the Gemini protocol was simple enough I could hack together this ad-hoc library in 3 days, it's still has a new library smell, and bound to be full of bugs. Feel free to issue a report for behavioral bugs, incorrect/unclear documentation, or even reach out to recommend anything you think would improve it!
Drop this project in a place that ASDF can see it - I personally use
~/quicklisp/local-projects/ so that quicklisp pulls in its
dependencies, alexandria, cl+ssl, puri, and trivial-sockets.

;; As a footnote, gmi-too-many-requests is a child type of gmi-error.

* (gemini-request "//example.com" :proxy "proxy.example.com")
* (gemini-request "//example.com"
:proxy '("proxy-example.com" 8000))
* (let ((*gemini-default-proxy* "proxy-example.com"))

;; You can choose whether to verify SSL certificates (for example,
;; expressly allowing self-signed certificates, or forcing servers
;; to be signed by a trusted root authority). Recommended reading
CL+SSL's MAKE-SSL-CLIENT-STREAM for all valid keyword arguments except
for EXTERNAL-FORMAT:
* (gemini-request "//self-signed.example.com" :ssl-options '(:verify nil))
;; You can use gemini-request-stream to return an input stream as the
;; primary value instead of the body. For text/* mimetype responses,
;; the stream is a flexi-stream with the automatically configured
;; external format, and for other responses, it's a raw octet stream.
