The Perl Toolchain Summit needs more sponsors. If your company depends on Perl, please support this very important event.
    The util/update-rule-pmc script is used to
    generate lib/Pugs/Grammar/Rule.pmc from
    this file.

    This script does the following:

    Use v6.pm to compile this file and
    post-process it after compiling:
    - remove all references to:
        Data::Bind
    - replace the header with:
        package Pugs::Grammar::Rule;
        use utf8;
        no strict 'refs';
        use Pugs::Runtime::Match;
        use Pugs::Runtime::Regex;
    The post-processing thing is done
    by the Perl 5 script util/patch-rule-pmc.pl
