+// 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).
