-Usage: you can run this script with any valid combination
-of the following environment variables (in any order):
-  KERNEL - the kernel image file to use
-  ROOTFS - the rootfs image file or nfsroot directory to use
-  MACHINE - the machine name (optional, autodetected from KERNEL filename if unspecified)
-  Simplified QEMU command-line options can be passed with:
-    nographic - disables video console
-    serial - enables a serial console on /dev/ttyS0
-    kvm - enables KVM when running qemux86/qemux86-64 (VT-capable CPU required)
-    kvm-vhost - enables KVM with vhost support when running qemux86/qemux86-64 (VT-capable CPU required)
-    publicvnc - enable a VNC server open to all hosts
-  qemuparams="xyz" - specify custom parameters to QEMU
-  bootparams="xyz" - specify custom kernel parameters during boot
-
-Examples:
-  $MYNAME qemuarm
-  $MYNAME qemux86-64 core-image-sato ext4
-  $MYNAME qemux86-64 wic-image-minimal wic
-  $MYNAME path/to/bzImage-qemux86.bin path/to/nfsrootdir/ serial
-  $MYNAME qemux86 iso/hddimg/vmdk/qcow2/vdi/ramfs/cpio.gz...
-  $MYNAME qemux86 qemuparams="-m 256"
-  $MYNAME qemux86 bootparams="psplash=false"
-  $MYNAME path/to/<image>-<machine>.vmdk
-  $MYNAME path/to/<image>-<machine>.wic

-Using OE images with QEMU
-=========================
-
-OE-Core can generate qemu bootable kernels and images with can be used 
-on a desktop system. The scripts currently support booting ARM, MIPS, PowerPC
-and x86 (32 and 64 bit) images. The scripts can be used within the OE build 
-system or externaly.
-
-The runqemu script is run as: 
-
-   runqemu <machine> <zimage> <filesystem>
-
-where:
-
-   <machine> is the machine/architecture to use (qemuarm/qemumips/qemuppc/qemux86/qemux86-64)
-   <zimage> is the path to a kernel (e.g. zimage-qemuarm.bin)
-   <filesystem> is the path to an ext2 image (e.g. filesystem-qemuarm.ext2) or an nfs directory
-   
-If <machine> isn't specified, the script will try to detect the machine name 
-from the name of the <zimage> file.
-
-If <filesystem> isn't specified, nfs booting will be assumed.
-
-When used within the build system, it will default to qemuarm, ext2 and the last kernel and 
-core-image-sato-sdk image built by the build system. If an sdk image isn't present it will look
-for sato and minimal images.
-
-Full usage instructions can be seen by running the command with no options specified.
-
-
-Notes
-=====
-
- - The scripts run qemu using sudo. Change perms on /dev/net/tun to 
-   run as non root. The runqemu-gen-tapdevs script can also be used by
-   root to prepopulate the appropriate network devices.
- - You can access the host computer at 192.168.7.1 within the image.
- - Your qemu system will be accessible as 192.16.7.2.
- - The script extracts the root filesystem specified under pseudo and sets up a userspace
-   NFS server to share the image over by default meaning the filesystem can be accessed by
-   both the host and guest systems.
