0012 == UPDATE HISTORY ==
0013 2018-02-20 // Nibaldo González <nibgonz@gmail.com>
0014
0015   Fix '$' symbol, highlighted as 'dsError' by C++ (isocpp.xml).
0016   Update syntax for Bison (3.0.4):
0017    - Add declarations, directives in rules and the '@' variable.
0018    - Allow a tag in '%union', declarations in multiple lines and
0019      grammar declarations in the grammar rules section.
0020    - The ';' char is not necessary to finish a rule. Allow '; |'
0021      within rules.
0022   Add mimetypes and extensions '*.ypp' & '*.y++'.
0023
0024 2007-10-01 // Sebastian Pipping <webmaster@hartwork.org>
0025
0026   Added: Extension "*.yy" for Bison
