# Generated by GOLD Parser Builder using Mybuild program template.

# Symbol constructors for 'ConfigFile' grammar.

#
# Each terminal symbol is converted by the corresponding constructor (if any).
# Constructor is a function named '$(gold_grammar)_create-<ID>' (where ID is
# a unique symbol identifier) with the following signature:
#
# Params:
#   1. A list of decimal char codes representing the token.
#
# Return:
#   The converted value, which is then passed as an argument to a production
#   function of the rule containing that symbol in its RHS.
#
# If constructor for some symbol is not defined then the default behavior
# is used, which is to decode an input by replacing all printable characters
# with their values and the rest ones with spaces.
#
# Constructor may also use a special 'gold_default_create' function to get
# the default value.
