Get CPU info (Android devices)

Sometimes you need to get detailed information about your processor on your Android device.  You cat get from proc file system. For example, to see what floating point unit you really have on your device you can check the output of the following command:
db shell cat /proc/cpuinfo
Some units are compatible with another: 
vfp < vfpv3 < neon
It meas if you have neon, that vfpv3 will work for you as well.
