Then paths > containing = are expressable as ./foo=bar This is a little more complicated than I'd like (we have a few too many different ad hoc parsers and novel grammars in Debian), but I think it's unavoidable at this point without breaking backward compatibility in ways that aren't worth it. So, looks good to me. Next step is for someone to get a chance to write the language. (I'll tag the bug accordingly.) -- Russ Allbery ([email protected]) <http://www.eyrie.org/~eagle/>
