=head1 DESCRIPTION

This is a version of C which converts underscores in
attribute names to dashes when generating command line flags.

You can selectively disable this on a per-attribute basis by supplying
a L argument with
the command flag you'd like for a given attribute. No underscore to
dash replacement will be done on the C.
