Qemu is a fast processor emulator: currently the package supports arm, cris, i386, m68k (coldfire), microblaze, mips, powerpc, sh4, sparc and x86-64 emulation. by using dynamic translation it achieves reasonable speed while being easy to port on new host cpus.

this is a transitional package depending on the system and user mode emulation binaries. you can remove it once the upgrade is complete and nothing depends on it.
