+%% This program is used to generate a header file with data for
+%% normalizing denormalized unicode.
+
+%% The C header is generated from a text file containing tuples in the 
+%% following format:
+%% {RevList,Translation}
+%% Where 'RevList' is a reversed list of the denormalized repressentation of
+%% the character 'Translation'. An example would be the swedish character 
+%% '�', which would be represented in the file as:
+%% {[776,111],246}, as the denormalized representation of codepoint 246
+%% is [111,776] (i.e an 'o' followed by the "double dot accent character 776),
+%% while '�' instead is represented as {[776,97],228}, as the denormalized 
+%% form would be [97,776] (same accent but an 'a' instead).
+%% The datafile is generated from the table on Apple's developer connection
+%% http://developer.apple.com/library/mac/#technotes/tn/tn1150table.html
+%% The generating is done whenever new data is present (i.e. dec.dat has 
+%% to be changed) and not for every build. The product (the C header) is copied
+%% to $ERL_TOP/erts/beam after generation and checked in.
+%% The program and the data file is included for reference.
