I must admit that I've been writing a Linux dictionary of late and have come
across this problem. Anyway, rpm -qa --info and then pipe it into the
program below. Please note that this is very roar and that I also have a few
other scripts/programs that are designed to transform it into something much
neater (more suitable for the dictionary). Also, this could be an old/er
version of the program. Could do with some nipping up.
