+"Note that you can use :: only for appending one item per line to a list and "
+"that you should not use it in combination with the scope syntax. (The scope "
+"syntax implicit insert ::) Using both syntaxes together will trigger a bug "
+"which some users unfortunately relay on: An option with the unusual name "
+"\"<literal>::</literal>\" which acts like every other option with a name. "
+"These introduces many problems including that a user who writes multiple "
+"lines in this <emphasis>wrong</emphasis> syntax in the hope to append to a "
+"list will gain the opposite as only the last assignment for this option "
+"\"<literal>::</literal>\" will be used. Upcoming APT versions will raise "
+"errors and will stop working if they encounter this misuse, so please "
+"correct such statements now as long as APT doesn't complain explicit about "
+"them."
