1. Reports bugs in the Debian distribution. reportbug is a tool designed to make the reporting of bugs in Debian and derived distributions relatively painless. Its features include: * Integration with the mutt, af, and mh/nmh mail readers. * Access to outstanding bug reports to make it easier to identify whether problems have already been reported. * Support for following-up on outstanding reports. * Optional PGP/GnuPG integration. reportbug is designed to be used on systems with an installed mail transport agent, like exim or sendmail; however, you can edit the configuration file and send reports using any available mail server.
