Pod::Coverage.pm 0.06 is required to do pod coverage.  This will tell
you how well you have documented your modules.  Pod coverage will be
unavailable until you install this module, available from CPAN.  In the
meantime, you may continue to use the rest of Devel::Cover.

I like to have some idea of the distribution of this software.  To that end I
would be very grateful for mail from you.  This will be used only to satisfy my
curiosity and to help me make decisions which may involve changes to the
module.

If you can run perlbug you can send me a success report with "make ok".
Failure reports with "make nok" are also appreciated.

If you have any questions or comments, mailing list details are available in the
README file, or send mail to me directly.
