-// Description:
-// Reads and parses the Unicode collation value table and writes out a C++ source file
-// containing the data in a form that can be used by the EPOC collation system.
-//
-// The program reads three files or one compositive files:
-//
-// Three files (by default):
-// 1. Base keys (maps single Unicode values to single collation key values): must be in the same format as
-// basekeys.txt, supplied with the Standard Unicode Collation system
-//
-// 2. Composite keys (maps single Unicode values to strings of collation keys): must be in the same format as
-// compkeys.txt, supplied with the Standard Unicode Collation system
-//
-// 3. Strings (maps strings of Unicode values to single collation keys OR strings of collation keys): must be in the
-// same format as compkeys.txt, except that there can be any number of Unicode characters at the start of the line,
-// space-separated and each exactly 4 hex digits.
-//
-// One compositive files (with option /a):
-// 1. All Keys (combine above three files into one file): must be in the same format as allkeys.txt, supplied with the Standard Unicode Collation system (after Unicode 3.0).
