This program takes the F<RangeMessage.xml> and makes the data
structure to hard-code into L<Business::ISBN::Data>.

The module ships with the F<RangeMessage.xml> that was current as of
the release of the module, but it also hard-codes the same data. That
way, the module has the data even if the XML file disappears. The
module can also use any F<RangeMessage.xml> you specify, which allows
you to use updated (or even past) data. The hard-coded data always
gets you back to that for the release.


This module lives in a Github repository:
