Well, the individual members are fairly self-explanatory, don't you
think? Ethan's big on mnemonic names, and for a very good reason.

You might want to check out some module and use as example though.
mod_gearman provides a good resource, as does NDOUtils and Merlin.
Livestatus is pretty nifty, but unless you're mentally equipped to
follow the tons and tons of C++ boilerplate I advise against using
it as anything but an excellent backend to your data.

At http://git.op5.org/git/?p=nagios/merlin.git;a=summary you'll
find the merlin source-code. If you're not git-literate you might
want to download a snapshot. "module.c" and "hooks.c" has most of
the code that handles nebstruct type objects.

It's the "char *" argument to your module's nebmodule_init() function.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
