 == UPDATE HISTORY ==
+2018-02-20 // Nibaldo González <nibgonz@gmail.com>
+
+  Fix '$' symbol, highlighted as 'dsError' by C++ (isocpp.xml). 
+  Update syntax for Bison (3.0.4):
+   - Add declarations, directives in rules and the '@' variable.
+   - Allow a tag in '%union', declarations in multiple lines and 
+     grammar declarations in the grammar rules section.
+   - The ';' char is not necessary to finish a rule. Allow '; |' 
+     within rules.
+  Add mimetypes and extensions '*.ypp' & '*.y++'.
