There's now a second external plugin, the [[rst]] plugin, written in
python. It uses a `proxy.py`, a helper library for ikiwiki python plugins.

## How external plugins use XML RPC
stdout, also using XML RPC. After reading a command, and before returning
the result, the plugin can output XML RPC requests of its own, calling
functions in ikiwiki. Note: *Never* make an XML RPC request at any other

When ikiwiki starts up an external plugin, the first RPC it will make
is to call the plugin's `import()` function. That function typically makes

its configuration. External plugins can use the `getvar` and `setvar` RPCs
to access any such global hash. To get the "url" configuration value,
call `getvar("config", "url")`. To set it, call

undef/NULL/None. There is an extension to the protocol that supports this,
