Okay, that makes sense for cluster options. I'm still not sure it makes sense to put local options there, or to put meta-attributes for alerts, resources, and ops there.

I'm not at that point yet, still finishing up cluster options, but the rest should move faster with the infrastructure in place and the approach settled on.

That's basically the conundrum. Output is the only thing we're dealing with (there's no meaningful processing otherwise), but the output functions need access to an array that lives in libcrmcommon. There are many ways to approach this that would work. The question is which one's the cleanest and most in line with our existing code.

It looks like doxygen implements its own C source scanner. I wonder if it has issues with variadic macros.

I assume you are building without -DPCMK__WITH_ATTRIBUTE_OUTPUT_ARGS, right? In that case, PCMK__OUTPUT_ARGS is defined to nothing. So, that's weird.

How do you feel about a new lightweight CLI tool called something like pcmk_option? I think I can get this into crm_attribute relatively easily. It's just that none of these are attributes.

Inform Fabio when it's fixed

Do we want the "list cluster options" command to go in libpacemaker, or libcrmcommon?
