FindMagic - Find magic blocks in random binary data

This script finds ext2, cramfs, romfs or other filesystems in binary firmware files from router manufacturers like netgear, d-link and linksys. It should work for any file distributed as a firmware or flash update to any x86 and or UNIX variant embedded system that linux can at least "see" or deal with. It can also find things like embedded bios code etc.. These firmware files usually have proprietary headers and other junk intermixed within them, making them such that they cannot be directly mounted with the 'mount' command. The script uses the linux/Solaris "file" command to examine every x block of data in the image.
