allow to define macros in the config file
Macros can be defined at the top of the configuration file: dir = "/var/gemini" cert = "/etc/keys" and re-used later, for example server "foo" { root "$dir/foo" # -> /var/gemini/foo cert "$cert/foo.pem" # -> /etc/keys/foo.pem }
define GMID_STRING and reuse-it
GMID_VERSION follows the CGI/FastCGI style, i.e. project_name/version. Define GMID_STRING with a more "human" variant "project_name version", and reuse that in the --help and --version codepath.
