 // IMMEDIATE TODO & IDEAS:
 //  - Add language specific filter (by default all but it can also passed
-//    with -lpy -lc -lrb) which would only parse python, c and ruby files.
+//    with -tpy -tc -trb) which would only parse python, c and ruby files.
 //  - By default its case insensitive but with passing -cs it tells that
 //    all matching should be done in case sensitive way.
 //  - Add pthreads and check how grep does it's magic.
 //  - Add Levenshtein distance for matching and expose distance as arg with
 //    something like -d5 which would allow distance of 5 on a match.
 //  - Allow DEBUG to be provided as environmental variable.
+//  - Added depth flag (-r means recursive, -l2 means 2 levels deep).
