# Autogenerated from a Treetop grammar. Edits may be lost.


# Reusable parts of Treetop (http://treetop.rubyforge.org/) grammar for package
# definitions in v1 format.

# Some aspects of this grammar are significantly dumber than they could be
# because:
#
#   * We want to treat statements as identically as possible to their
#     command-line equivalents.
#   * Treetop parse errors are pretty inscrutable at times and we can make
#     error messages clearer by validating a lot of the terminals ourselves.
