This is your code.
Read it: it’s exactly what’s going to happen.
No mysticism.
</p>
<p>
What’s going on?
<a href="https://man.openbsd.org/pledge.2">pledge(2)</a> makes sure
you’re only doing what you want to do: work with existing descriptors.
The rest is just HTTP.
Don’t want to work with HTTP?
Use <a href="https://kristaps.bsd.lv/kcgi">kcgi(3)</a> or equivalent.
</p>

<a href="https://man.openbsd.org/httpd.conf.5">httpd.conf(5)</a>
is so… <i>simple</i>.
Server tells us the name.
Listen tells us to listen.
Location tells us a location.
Where we have FastCGI.
Relative to the root.
</p>
<p>
Don’t like FastCGI?
Neither do we.
But we’re not using it for this example: in the next snippet,
we’ll use <a href="https://man.openbsd.org/slowcgi.8">slowcgi(8)</a> to
invoke our CGI.
So relax.

Wow. Very configure.
Compiles the script. Installs it.
Makes sure <a href="https://man.openbsd.org/slowcgi.8">slowcgi(8)</a> and of
course <a href="https://man.openbsd.org/httpd.8">httpd(8)</a> are running.
Done.
