The second half of the section "Loading/running an executable" is about
thw HWCAP stuff (look for "capability suffix").  In the summary I have
this point:

* If capability-optimized ISA/ABI-compatible library variants are desired,
  they can be build just as today, only under the (same) multiarch
  suffix.  They could be packaged either within a single pacakge,
  or else using multiple packages (of the same multiarch type).

If you feel this could be made clearer, I'd appreciate any suggestions :-)
