Tracking Locations
==================

   Though grammar rules and semantic actions are enough to write a fully
functional parser, it can be useful to process some additionnal
informations, especially symbol locations.

   The way locations are handled is defined by providing a data type,
and actions to take when rules are matched.

Location Type

Specifying a data type for locations.

Actions and Locations

Using locations in actions.

Location Default Action

Defining a general way to compute locations.
