I'm going to go through and do paragraph-level labels for every EAPI
dependent feature on the eapi-3 branch.

I'm using this for development:

    \newcommand{\featureref}[1]{\b{feat:#1} on page~\pageref{feat:#1}}
    \newcommand{\compactfeatureref}[1]{\b{feat:#1}~p\pageref{feat:#1}}
    \newcommand{\featurelabel}[1]{\label{feat:#1} \visiblelabel{feat:#1} }
    \newcommand{\visiblelabel}[1]{\b{[#1]}}

I've attached a demonstration diff covering EAPI 1 things.

Is this going to work, or do I need to change how I'm doing anything?
Can you suggest a better \featurelabel that does the margin box thing
and that will work even if placed in an \item or \table or whatever?

Thanks,
