+* Description:
+* This file contains dependencies that the collation run-time doesn't normally
+* need. This mainly contains resource bundle usage and collation meta information
+*
+* Modification history
+* Date Name Comments
+* 1996-1999 various members of ICU team maintained C API for collation framework
+* 02/16/2001 synwee Added internal method getPrevSpecialCE
+* 03/01/2001 synwee Added maxexpansion functionality.
+* 03/16/2001 weiv Collation framework is rewritten in C and made UCA compliant
+* 12/08/2004 grhoten Split part of ucol.cpp into ucol_res.cpp
+* 2012-2014 markus Rewritten in C++ again.
