=head1 NAME
Data::Hopen::Tool - Base class for packages that know how to process files
=head1 SYNOPSIS
A tool knows how to generate a command or other text that will cause
a build system to perform a particular action on a file belonging to a
particular language.
A tool is a L<Data::Hopen::G::Op>, so may interact with the current
generator (L<Data::Hopen/$Generator>).  Moreover, the generator will
get a chance to visit the op after it is processed.
Maybe TODO:
    - Each Generator must specify a list of Content-Types (media types)
        it can consume.  Each Tool must specify a specific content-type
        it produces.  Mismatches are an error unless overriden on the
        hopen command line.
