=head1 SYNOPSYS

gurpm::RPMProgressDialog is a widget for gurpmi, rpmdrake (drakx already has its own)
that presents a global progress bar.

=head1 USAGE

How to use:

 my $w = gurpm::RPMProgressDialog->new:
 #$w->change_widget(Gtk2::Box->new);
 label(N("Preparing packages installation..."));
 ... # compute packages to install/remove...
 $w->init_progressbar;
 urpm::main_loop::run($urpm, $state, $nb, \@ask_unselect, {
       trans_log => &gurpm::RPMProgressDialog::callback_download,
       inst => \&gurpm::RPMProgressDialog::callback_inst,
       trans => \&gurpm::RPMProgressDialog::callback_inst,
       uninst => \&gurpm::RPMProgressDialog::callback_inst,
       ....
