=head1 NAME

progress-any-eg-progressbar-06-reusing-task - Reusing the same task to track progress of two activities

=head1 VERSION

This document describes version 0.005 of progress-any-eg-progressbar-06-reusing-task (from Perl distribution Progress-Any-Examples), released on 2020-07-09.

=head1 SYNOPSIS

 % progress-any-eg-progressbar-06-reusing-task [file_size1=10000] [file_size2=30000]

=head1 DESCRIPTION

This example script shows the progress of simulated downloading of two files
(the file sizes can be set via argument). The progress of each download will be
tracked with the same task: C<download>.

After the downloading of the first file is complete, we perform a C<reset()>
(a.k.a. C<< update(pos => 0) >>) to the task to change its state from
C<finished> to C<started> again.

Also notice the use of C<force_update> argument in the C<update()> to refresh
the progress bar with a "Downloaded xxx" message.
