# This is a full BNF grammar for the task command line. It is intended that a
# future release of task will incorporate a complete lexer/parser implementing
# this grammar, which will allow for more sophisticated command lines, for
# example:
#
# task delete 1 2 4-7
# task add pri:H pro:X -- pro pri 1 ///
