/** This tool is used to managed translation file.
*	I work with two different file format :
*		- phrase file witch contain a complex grammar description
*		- string file withc contain only pair of identifier / string value.
*	
*	This tool can do 6 different work :
*		- make diff string file file for each language from a reference string file.
*		
*		- merge the translated diff string file into there respective string file after
*			translation
*
*		- make diff phrase file for each language from a reference phrase file
*
*		- merge the translated diff phrase file into there respective phrase file after
*			translation
*
*		- make clause diff for each language by examining phrase files. Add comments
*			in the diff files for phrase parameter information.
*
*		- merge clause diff in all the clause file.
*
*		- remove "\*OLDVALUE: \*\/" from clause file or phrase file
*
*
*	Before invocation, you must be in the translation repository (see localisation_system_in_ryzom.doc)
*	Invocation should be as folow :
*		trans_tool make_string_diff 
*		trans_tool merge_string_diff 
*		trans_tool make_words_diff
*		trans_tool merge_words_diff 
*		trans_tool make_phrase_diff
*		trans_tool merge_phrase_diff
*		trans_tool make_clause_diff
*		trans_tool merge_clause_diff
*		trans_tool clean_string_diff
*		trans_tool clean_words_diff
*		trans_tool clean_clause_diff
*		trans_tool clean_phrase_diff
*		trans_tool make_phrase_diff_old
*		trans_tool merge_phrase_diff_old
*		trans_tool forget_phrase_diff
*		trans_tool update_phrase_work
