-This is use to enable an accelerator, in kvm,xen,tcg.
-By default, it use only tcg. If there a more than one accelerator
-specified, the next one is used if the first don't work.

+@item accel=@var{accels1}[:@var{accels2}[:...]]
+This is used to enable an accelerator. Depending on the target architecture,
+kvm, xen, or tcg can be available. By default, tcg is used. If there is more
