// Note: Be patient, getting these results take a while, probably due to log analyzing on Launchpad's end.
//       Sometimes you have to give it more than one try.
// NOTE: I have not yet tackled pagination, so you may have problems if you browse a big package!
// Patches and comments are welcome!

// To get more detailed stats, including very nice graphs, see this ppa:
// https://launchpad.net/~jfi/+archive/ubuntu/ppastats

// Configuration options:
var print_n_daily = GM_getValue('config_print_n_daily', 3);

// To change config, uncomment this:
//GM_setValue('config_print_n_daily', print_n_daily=15);
// This should preserve the value, even when the script updates.
// Go back to defaults with: (requires two refreshes)
//GM_deleteValue('config_print_n_daily');
