Kindof reminds me of Scapy for binary file formats!
Mr. Crowbar is a Django-esque model framework that makes it super easy to work with proprietary binary formats while reverse engineering. File formats are described with Python classes that allow ORM-like free modification of structures and properties, which in turn can be validated and converted back to the binary equivalent at any time. The eventual goal is to provide a library for storing file format information that retains the readability of a text file, while providing instant read/write support for almost no cost.[…]
