You guys aren't digging what this SRFI is, I think: It's a
*distribution format*.  The idea is that you send this stuff to your
friends or download it from somewhere, and then let your Scheme
implementation slurp it into its package library or whatever, possibly
(and probably) translating it into a format more suitable for its
internal processing.  As part of this step, you can extract the
exports and store them in some fancy index or whatever.  Possibly,
this isn't explained very well, and we need your help clearing up
misunderstandings.

I don't expect PLT Scheme or Chez or Scheme 48 to change their module
systems much or to stop developing new ones as a result of this
SRFI---rather I expect that their authors will implement "translators"
from and to the distribution format specified here.
