   1 # Syntax definition for some C++-specific patterns
   2 #
   3 # NOTE: this is *NOT* intended to be a complete definition of the language's
   4 # syntax! Providing a full language grammar is overkill, because the intended
   5 # use case is finding/replacing string patterns. This task does not require a
   6 # full parse tree, and having one makes the task considerably more complicated.
   7 # See the accompanying README.md for more info.
