macro names can be reserved words

fix macro example

document the c-like handling of strings

don't expand macros inside the quotes Now that we have this auto concat string thingy, macros can simply expand to standalone strings in place, as single words. Forgot to point it out in previous commits, but now we can cert = "/etc/keys" server "foo" { cert $cert "/foo.crt" ... }

align

[config] concat two or more strings next to each others

document macros: both -D and syntax

don't require the strict order macro > options > servers

add -D to define macros from the cmd line

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 }

trailing whitespaces

give a name to the anonymous union

sync the usage; while there also change order and capitalize

mention -V/--version and --help in the manpage

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.
