14  operating systems (eg. NetBSD) run as if they were running on a real machine.  
15    MIPS processors are emulated using either a simple binary translation
16    layer ("recompilation"), which is used on Alpha and i386 hosts, or by
17    traditional interpretation (very very slow, but works on any host platform).
18    
19    ARM and PowerPC processors are emulated using a newer dynamic translation
20    system. Performance is somewhere between traditional interpretation and
21    dynamic recompilation; however, the dynamic translation system used in
22    GXemul does NOT require platform-specific back-end code. In plain English,
23    this means that the dyntrans system works on any host platform.

26    much from it.)
