+Description: Include the Debian version in our identification
+ This makes it easier to audit networks for versions patched against
+ security vulnerabilities.  It has little detrimental effect, as attackers
+ will generally just try attacks rather than bothering to scan for
+ vulnerable-looking version strings.  (However, see debian-banner.patch.)
