So, that's kind of what I was trying out. One idea was to put the help
strings in a separate module and just reference them in the source code. My
concern however is that if they're not with the code they wont get updated
which things change. Instead, if we move the entire flag people are still
forced to notice the help string and that its wrong when they tweak things.

Its not perfect though, and ideas are very welcome. The basic problem is
that if you try to configure SSL, there are a whole heap of different
options available, and its not clear how they interact and what you need to
twiddle to make things work unless you read the code.
