1 things to do (eventually.) patches are welcome, thanks!
3 - provide knobs for some features of the gemtext -> HTML conversion,
4 automatic preview of images for example.
5 - support for using client-side certificates.
6 - `location' support for blocking certain sub-trees (or maybe even
7 location-dependant proxying!)
8 - try to extract the page title (need a separate per-request buffer.)
9 - `listen' directive: allow to listen on (multiple) sockets, be UNIX
11 - extend to support gopher and/or spartan?
12 - simplify process IPC: proc.c is cool but provides more than we need;
13 there's no web of process that communicates between each others, just
14 a parent and (some) proxy processes.
15 - make the build from the tarball works without building `template'.
16 - generate ids for headers for ease of linkability;
