+# fix_permissions - fixes permissions on Android data directories after upgrade
+# shade@chemlab.org
+#
+# 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]
