#
# DESCRIPTION
#   Definition of the parser grammar for the Template Toolkit language.
#
#   This grammar teken ftom Template perl library and modified by Serguei
#   Okladnikov to integrate asynchronous EVENT, ASYNC and AWAIT operators
#
# AUTHOR
#   Andy Wardley <abw@wardley.org> 
#   Serguei Okladnikov <oklaspec@gmail.com> (EVENT/ASYNC/AWAIT and some more)
#
# HISTORY
#   Totally re-written for version 2, based on Doug Steinwand's 
#   implementation which compiles templates to Perl code.  The generated
#   code is _considerably_ faster, more portable and easier to process.
#
# WARNINGS
#   Expect 1 reduce/reduce conflict.  This can safely be ignored.
#   Now also expect 1 shift/reduce conflict, created by adding a rule
#   to 'args' to allow assignments of the form 'foo.bar = baz'.  It
#   should be possible to fix the problem by rewriting some rules, but
#   I'm loathed to hack it up too much right now.  Maybe later.
