Yann E. MORIN - Feb. 3, 2013, 2:06 p.m.
Untested for other architectures, so only enabled for known-working ones.

We explicitly disable all features that depends on other packages,
for now. Such features will be added one by one in the next patches.
Features that do not rely on external packages are explicitly enabled
to catch the dependencies on toolchain features early.

+	  QEMU is a generic and open source machine emulator and virtualizer.
+	  
+	  When used as a machine emulator, QEMU can run OSes and programs made
+	  for one machine (e.g. an ARM board) on a different machine (e.g.
+	  your own PC). By using dynamic translation, it achieves very good
+	  performance.
+	  
+	  When used as a virtualizer, QEMU achieves near native performances
+	  by executing the guest code directly on the host CPU. QEMU supports
+	  virtualization when executing under the Xen hypervisor or using the
+	  KVM kernel module in Linux. When using KVM, QEMU can virtualize x86,
+	  server and embedded PowerPC, and S390 guests.
