Great. You should possibly look at the simple ones (echo, ipv4-to-int,
etc) first.

Then you'll possibly need a a "prepare" callback in order to process the
quite complicated argument list using GLib's option parser into
structure that can then be passed to the core of the format
functionality.

The point of the prepare callback is to avoid having to do expensive
parameter processing during runtime (when it is expensive) and do it
early on during template compilation.

Currently grep/if use this functionality to compile the filter
expression into its internal representation.
