Same as traditional shared objects, it now looks like this:

    varnish = x.y.z-r
    varnish(x86-64) = x.y.z-r
    libvarnishapi.so.1()(64bit)
    libvarnishapi.so.1(LIBVARNISHAPI_2.0)(64bit)
    varnishd(abi) = sha1
    varnishd(vrt) = a.b
    vmod(blob)(64bit) = x.y.z-r
    vmod(directors)(64bit) = x.y.z-r
    vmod(purge)(64bit) = x.y.z-r
    vmod(std)(64bit) = x.y.z-r
    vmod(vtc)(64bit) = x.y.z-r

Maybe varnishd(*) provides should be ISA-bits-aware too.
