-      FDUPES uses md5sums and then a byte by byte comparison to finde duplicate
-      files within a set of directories.
+      FDUPES compares inodes' stats, hash sums, and byte by byte file
+      contents to find duplicate files within a set of directories and
+      then applies various actions to those sets, e.g.:
+      * remove some of the duplicates,
+      * turn all the files in a set into hardlinks.
