=head1 TITLE
valid-date-class - See whether a module can be used as a date class by __format().
=head1 SYNOPSIS
 valid-date-class Date::Tolkien::Shire
 valid-date-class -help
 valid-date-class -version
=head1 OPTIONS
=head2 -blib
If this Boolean option is asserted, the equivalent of C<use blib;> is
done before analyzing any modules speified.
=head2 -help
This option displays the documentation for this script. The script then
exits.
=head2 -version
This option displays the version of this script. The script then exits.
=head1 DETAILS
The L<Date::Tolkien::Shire::Data|Date::Tolkien::Shire::Data>
L<__format()|Date::Tolkien::Shire::Data/__format> subroutine will take
an object as its first argument, provided that object implements the
proper methods.
This Perl script takes as its arguments the names of one or more Perl
packages. Each package is loaded and checked to see if it has all the
required methods. If it does not, the missing methods are listed. If it
does, a success message it displayed.
The exit status is the number of packages that fail the test, or C<250>,
whichever is smaller.
