+This directory contains the source code of ICU 4.6.1 for C/C++.

+Local Modifiations:
+1. Modified stringpiece.cpp to disable StringPiece::npos in Visual
+ Studio 2010 and 2012, which is required in order to build in those
+ environments. Chromium made the same change to their
+ stringpiece.cpp.
Page Speed uses ICU to enable IDN
