=head2 retry

Setter/getter for the current retry count. Used by both the pragma and
the command-line option to store the argument value.

=head2 retry_pragma
Implements the actual code: stacks a call to C<mech->retry> on the
outgoing code stream, or a call to C<fail> if the argument is not 
a number.

=head2 validate_options

Generates a virtual C<%%retry> pragma for the value given on the command line.

=head1 OPTIONS

=head2 --retry

Allows you to specify a global retry count for the input file to be
processed. If the input file contains C<%%retry> pragmas, the count
will be reset as these pragmas are encountered.

=head1 PRAGMAS

=head2 %%retry

Set the retry count immediately to the new count specified as the
argument.

    %%retry 3
    http://unsteady.org/ /.../ Y Look for expected text
    %%retry 0
    http://steady.org/   /.../ Y Same text

A retry count of zero means that the fetch will not be retried.

=head1 DIAGNOSTICS

=head2 C<< "retry count '$args' is not a number >>

Issued by the generated test code if Perl can't parse the retry
count (either from a pragma or the command line) as a valid number.


=head1 CONFIGURATION AND ENVIRONMENT

App::SimpleScan::Plugin::Retry requires no configuration files or environment variables.


=head1 DEPENDENCIES

App::SimpleScan, WWW::Mechanize::Pluggable::Retry.


=head1 INCOMPATIBILITIES

None reported.


=head1 BUGS AND LIMITATIONS

This only retries fetch failures; a more flexible means of testing 
"did it work?" is probably in order.

C<bug-app-simplescan-plugin-retry@rt.cpan.org>, or through the web interface at
