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  - optional nav bar with buttons like "up one level", "home" or "root"
6    (see the "nav" branch.)
7  - support for using client-side certificates.
8  - `location' support for blocking certain sub-trees (or maybe even
9    location-dependant proxying!)
10  - try to extract the page title (need a separate per-request buffer.)
11  - `listen' directive: allow to listen on (multiple) sockets, be UNIX
12    or TCP ones.
13  - extend to support gopher and/or spartan?
14  - simplify process IPC: proc.c is cool but provides more than we need;
15    there's no web of process that communicates between each others, just
16    a parent and (some) proxy processes.
17  - make the build from the tarball works without building `template'.
18  - generate ids for headers for ease of linkability;
