+# for a more complete explanation, nicely marked up and with examples.
+#
+#
+# Semantic action rules for nonterminal symbols can be specified here by
+# creating a method prefaced with "n_" for that nonterminal. For
+# example, "n_exec_stmt" handles the semantic actions for the
+# "exec_stmt" nonterminal symbol. Similarly if a method with the name

+# all of its children are called.
+#
+# After a while writing methods this way, you'll find many routines which do similar
+# sorts of things, and soon you'll find you want a short notation to
+# describe rules and not have to create methods at all.
+#
+# So another other way to specify a semantic rule for a nonterminal is via
+# one of the tables MAP_R0, MAP_R, or MAP_DIRECT where the key is the
+# nonterminal name.
+#
+# These dictionaries use a printf-like syntax to direct substitution
+# from attributes of the nonterminal and its children..
+#
+# The rest of the below describes how table-driven semantic actions work
+# and gives a list of the format specifiers. The default() and
+# template_engine() methods implement most of the below.
+#
+# We allow for a couple of ways to interact with a node in a tree.  So
+# step 1 after not seeing a custom method for a nonterminal is to
+# determine from what point of view tree-wise the rule is applied.
+
+# In the diagram below, N is a nonterminal name, and K also a nonterminal
+# name but the one used as a key in the table.
+# we show where those are with respect to each other in the
+# AST tree for N.

+#
+#   The default table is TABLE_DIRECT mapping By far, most rules used work this way.
+#   TABLE_R0 is rarely used.
+#
+#   The key K is then extracted from the subtree and used to find one
+#   of the tables, T listed above.  The result after applying T[K] is

+#   engine.
+#
+#   Escapes in the format string are:

+#         integer representing a node index.
+#
+#     %p  like %c but sets the operator precedence.
+#         Its argument then is a tuple indicating the node
+#         index and the precidence value, an integer.
+#
+#     %C  evaluate children recursively, with sibling children separated by the
+#         given string.  It needs a 3-tuple: a starting node, the maximimum
+#         value of an end node, and a string to be inserted between sibling children
+#
+#     %,  Append ',' if last %C only printed one item. This is mostly for tuples

+#         other tuples. The specifier takes no arguments
+#
+#     %P same as %C but sets operator precedence.  Its argument is a 4-tuple:
+#         the node low and high indices, the separator, a string the precidence
+#         value, an integer.
+#
