1 CaseEquivalence.pl takes as its input the file UnicodeData-3.0.0.txt on the standard input stream and produces as output one of the following on the standard output stream depending on the option -o{t|f|r|m}:

     2 

     3 -ot: produce a trie in C++ compilable format which gives a mapping for each Unicode character.

     4 -of: produce a mapping of characters to canonical case equivalent character

     5 -or: produce a list of canonical case characters and a list of what maps to each

     6 -om: as -or but does not print those mappings for which only one character needs to map.
