-*** parser header (%defines) is no longer mandatory (lalr1.cc)
+*** The parser header is no longer mandatory (lalr1.cc, glr.cc)
- In which case, if needed, the support classes are defined in the generated
- parser, instead of additional files (location.hh, position.hh and
- stack.hh).
+ Using %defines is now optional. Without it, the needed support classes
+ are defined in the generated parser, instead of additional files (such as
+ location.hh, position.hh and stack.hh).
-*** locations are no longer mandatory (lalr1.cc, glr.cc)
+*** Locations are no longer mandatory (lalr1.cc, glr.cc)
