Hi,

following a suggestion from Bug #479953[1] there are two new headers defined
for automated package maintenance emails, to make it easier for
Developers to filter mail from all the various tools in Debian sending
mail.

The headers follow the definition in the following few points:

a. Every tool can add X-whatever headers as it sees fit, but do not
bloat the mails unneccesarily.

b. Every tool sending automated mail to Debian Developers should add
headers of the form

X-Debian: $TOOL
X-Debian-Package: $PACKAGE

and so clearly mark that it is an automagic generated mail by
$TOOL and about $PACKAGE. Every bit more information, like what
script exactly did generate the mail, should be in seperate
X-whatever headers or the mail body.

The X-Debian-Package: header can be omitted if it is not possible to
name a specific source package for a mail, like when the mail is
about multiple packages.
