If this has already been discussed, please just point me to it; I must have missed it...
Yacc and ctags are provided by many different packages, and managed by update-alternatives, but there is no virtual package corresponding to either of them. I suspect there are other similar situations. I don't really want to say ``Build-Depends: bison, emacs20'', the packages that happen to provide those for me, and it doesn't feel right to list all the alternatives myself. And as far as I understand, these are not part of build-essentail or any essential packages. What should I do? Thanks.
