Description:

This package contains hardlink, an utility which consolidates duplicate
files in one or more directories using hardlinks.

hardlink traverses one or more directories searching for duplicate files.
When it finds duplicate files, it uses one of them as the master. It then
removes all other duplicates and places a hardlink for each one pointing
to the master file. This allows for conservation of disk space where
multiple directories on a single filesystem contain many duplicate files.

Since hard links can only span a single filesystem, hardlink is only
useful when all directories specified are on the same filesystem.
