# OpenRG Image Parser
OpenRG has a custom image file format, with headers and compression and config files. This utility extracts files from flat OpenRG images. It uses `mmap`'d IO to be fast, and validates checksums. It's also a decent piece of reference code for doing other things with OpenRG files.
### Usage
$ make
cc -march=native -O3 -std=c99 -pipe -fomit-frame-pointer -lz image-parser.c -o image-parser
$ ./image-parser /dev/mtdblock0
