TCP::Rebuild::App - the guts of the tcprebuild command

=head1 SYNOPSIS

  #!/usr/bin/perl
  use TCP::Rebuild::App;
  TCP::Rebuild::App->run;

use File::Spec;
use Getopt::Long qw(GetOptions);

  exit;
}

=head2 run

This method is called by F<tcprebuild> to do all the work.  Relying on it doing
something sensible is plain silly.
