 Change Log:
 ----------------------------------
+2.0a, 15-02-2014
+-Added multithreading support for @CUSTOM_COMMAND, use wildcards in multiple files for the same js code to 
+take advantage of this (performance may increase over 2.5 times)
+-Now a warning is given if a user javascript code (@CUSTOM_COMMAND) takes too much time to finish
+-Fixed small bug when applying patches with @COMMAND + --no-verbose where some std output should not be displayed
+----------------------------------
 2.0, 08-02-2014
 -Rewrite XmlTools fom the scratch from C# to C++ in order to increase (much!) the performance of the program
