=head1 NAME

Devscripts::Uscan::WatchFile - watchfile object for L<uscan>

=head1 SYNOPSIS

use Devscripts::Uscan::Config;
  use Devscripts::Uscan::WatchFile;
  
  my $config = Devscripts::Uscan::Config->new({
    # Uscan config parameters. Example:
    destdir => '..',
  });

# You can use Devscripts::Uscan::FindFiles to find watchfiles
  
  my $wf = Devscripts::Uscan::WatchFile->new({
      config      => $config,
      package     => $package,
      pkg_dir     => $pkg_dir,
      pkg_version => $version,
      watchfile   => $watchfile,
  });
  return $wf->status if ( $wf->status );
  
  # Do the job
  return $wf->process_lines;

=head1 DESCRIPTION
