I can sympathise with this.  I haven't really even tried to run
GLV-1.12556 because of the steps needed to run it!  I have only talked
with Sean some time ago, he pointed out some issues with the CGI
implementation in gmid, and so I took a look at how GLV implements them.

gmid at the moment shares the same problem of GLV-1.12556: it has
LibreSSL as dependency (which I don't regret by the way, it has such a
clean API it's almost a joy to use: compare the code in server.c to the
OpenSSL-specific bits in utils.c!)

[ I've started to develop a library to write Gemini clients and server
  that, among other things, has an abstraction over the specific TLS
  library: this helps for testing and should help with portability
  across different systems I hope. ]

The details of the CGI variable available are documented in the manpage,
under the CGI section, but there is also a test page I'm serving at:


I should probably link it in the README.  Note: that demo page it's
early this morning.

There is also a similar page for GLV-1.12556:


[ actually, my page is inspired from the GLV-1.12556 one, not the other
  way around of course! ]

I think I misunderstood your last mail then, apologies.

Anyway, talking about timing, earlier I was re-writing my `man' CGI
script from rc to Perl!  (I'm not familiar at all with the language, but
I'm slowly learning.)  If/when your module will be ready, I would like
to play with it.  I have a couple of CGI scripts written in different
languages, and I'm slowly re-writing the ones in shell/rc to perl.
