+====== fdupes ======
+This is a nice little tool helping to find duplicate files within a given directory.
+===== How Files Are Matched =====
+  - compare the **size** of the files
+  - compare their **MD5** sums
+  - if above matches, compare them **byte-by-byte**
+===== Usage =====
+Invocation is just as simple as eatin' pancakes:
+  fdupes -r -n /stuff
+compares all files within **/stuff** recursively (**-r**) omitting zero-length files (**-n**).
