I don't know all the details, but since most libsdl (Debian) back-ends, plus other software, depends on libsvga1, would it not be better to have
Conflicts: libsvga1
Replaces: libsvga1
as meta-data, instead of just
Conflicts: libsvga1 ?
Right now, svgalib1-libggi2 is just about uninstallable for this reason.
After all, if you're telling programmers to build against libsvga1-dev , then the functionality should really be pretty close.
Or is there added functionality in libsvga1 , which is still indispensable?
