I always get a bit concerned when I hear we'll factor out or just import
only the minimal code we need to support the minimal functionality we
need from an otherwise large complex body of code implementing an entire
RFC.

Maybe the code in libical is perfectly suited to extracting the snippets
we need (I don't know) but experience tells me complex code has complex
inter-dependencies and reducing libical to our minimal requirements
might be a significant effort. Is there really a problem with just
linking with the entire libical library even if it's more than we need?
