written in python for the sake of platform independence when operating on static binaries and libraries

Special thanks to

IDA for making it possible to write the code without actually understanding full internals
JLevin and *OS Internals Vol 1 for actually understanding the internals and specifics + writing documentation
arandomdev for guidance + code
