Well, if you're going to use a library, terminfo is the way to go. All
modern Posix systems should have it. As for terminal description files,
don't rely on that, because it varies wildly from system to system. Your
best bet is to either recognize known values of $TERM, or use a library
like terminfo that takes care of all the dirty details for you. It does
get very messy once you get down to the nitty gritty of how different
*nixes handle terminal capabilities.
