I rarely announce software, but this could be useful to DDs. Whenever I wanted to add tags or something to a bug report, I'd start my browser to http://www.debian.org/ -> Bug Reports -> Developers' information on manipulating bugs by email. Just to get the syntac right.
So I wrote debian-bts-control.el, an Emacs interface to build the email messages. It knows all the commands and their options with TAB completions. If you want to try it, install `dpkg-dev-el' from unstable, and do: M-x debian-bts-control Subsequent invocations add a directive to the same email message. Hope you like it! Peter
