-# original concept: http://blog.elsdoerfer.name/2009/05/25/android-fix-package-uid-mismatches/
-# implementation by: Cyanogen
-# improved by: ankn, smeat, thenefield, farmatito, rikupw, Kastro
-#
-# v1.1-v1.31r3 - many improvements and concepts from XDA developers.
-# v1.34 through v2.00 -  A lot of frustration [by Kastro]
-# v2.01	- Completely rewrote the script for SPEED, thanks for the input farmatito
-#         /data/data depth recursion is tweaked;
-#         fixed single mode;
-#         functions created for modularity;
-#         logging can be disabled via CLI for more speed;
-#         runtime computation added to end (Runtime: mins secs);
-#         progress (current # of total) added to screen;
-#         fixed CLI argument parsing, now you can have more than one option!;
-#         debug cli option;
-#         verbosity can be disabled via CLI option for less noise;;
-#         [by Kastro, (XDA: k4str0), twitter;mattcarver]
-# v2.02 - ignore com.htc.resources.apk if it exists and minor code cleanups,
-#         fix help text, implement simulated run (-s) [farmatito]
-# v2.03 - fixed chown group ownership output [Kastro]
-# v2.04 - replaced /system/sd with $SD_EXT_DIRECTORY [Firerat]
