nginx-confgen is a simple preprocessor and macro system for
L<nginx|http://nginx.org/> and nginx-like configuration files. It support
variable substitution, macro expansion and using the output of arbitrary
commands to generate config files.

=head2 Example

  pre_set $certdir /etc/nginx-certificates/;

  # Fetch the 'resolver' from /etc/resolv.conf
  pre_exec $nameserver "grep nameserver /etc/resolv.conf \\
                        | head -n 1 | sed 's/^nameserver //'";
  resolver $nameserver;

  # Convenient macro to create a HTTPS virtual host
  macro vhost $domain @aliases &block {
    server {
      listen [::]:443 ssl;
      server_name $domain @aliases;

      ssl_certificate     $certdir/$domain/fullchain.pem;
      ssl_certificate_key $certdir/$domain/privkey.pem;
      pre_if -f $certdir/$domain/ocsp.der {
        ssl_stapling_file $certdir/$domain/ocsp.der;
      }

      &block;
    }
  }

  vhost example.com www.example.com {
    root /var/www/example.com;
  }
