- reasoning - please play by the rules
  * we have a policy for commit messages
  * don't silently drop patches (gnutls), whenever we patch stuff it's usually
    done for a reason
  * don't upgrade security critical packages (gnutls) to development releases.
    upstream has a reason for not declaring them stable yet.
  * when told by a senior developer to consult oe@ _before_ pushing a change
    do so, don't ignore him (RP) and push anyway
