no, it definitely was 2011. in fact, i tried it precisely because i
remembered some (old) comments here said that.

is there some FAQ about this? one that doesn't assume i already know
the luarocks way, but specifically for "don't mess with my system"

fair enough. (i guess, but don't really care about windows tools;
when i have to ship a windows-friendly package, i include all
dependencies... hum, another reason to get a readable description of

if it shows the dependencies, i can just ignore what i already have.
or maybe a "don't care about versions, if it's require()able, it's

yeah, as long as it has a dry-run option, to let me see what is it
trying to do and do it myself, and if it's readable without having to
care about inner works of LuaRocks.
but what i'd really want is: from a rockspeck, print the dependency
tree (maybe pruned if i can register the 'already have' packages), and
the 'what goes where' of the specific package.
