shazer - find and hardlink duplicate files based on checksums
Generate a checksums file with your favorite shasum program and list
the space that could be recovered by hardlinking duplicate files.
Run with -v to list all duplicates, run with -x to create the hardlinks.

-a process already linked files too
-g globpat only consider files matching globpat ('%'->'*')
