I think we need to have it in one place only if at all possible, or we will encounter the situation where one version gets updated and the other does not. Doxygen correctly pulls it from either location (see alpm_initialize, etc.), but it is definitely nice to have in the header, so let's kill it from be_package.c in this case. We will come across it moving on, but we should also pick a format we plan to follow, as I've seen several: 1) Put first line on /** line, everything else follows after a newline. This is the most compact. 2) Same, but newline and empty line after first line. 3) Use @brief, then a empty line, then remaining text. Things also seem to have spaces between every part (brief, summary, params). 4) Compact but using @brief. I don't care- as I said, I'm letting you call the shots, but we should try and pick one and stick with it and eventually retrofit everything to work this way.

I say this because you should stick the above requiredby function in this group, and document that the contents MUST be freed by the caller as it is computed, not "gotten". (A list of strings apparently...not sure why it isn't pmpkg_t).
