Assistance with indexterm tags - index files aren't being generated.

Hello,

I've reviewed the documentation and some of the oreilly resources, and
I haven't been able to generate any of the index files that docbook
should make when it encounters <indexterm> tags.

Any recommendations or resources I should be reviewing that can help
me solve this issue?


I'm not passing any special commands to the docbook "compiler" and I'm
not sure if that's something I should be doing - much less what those
commands are.

Thanks,

ct
