Kaitai Struct: runtime library for Python
This library implements Kaitai Struct API for Python.
Kaitai Struct is a declarative language used for describe various binary data structures, laid out in files or in memory: i.e. binary file formats, network stream packet formats, etc.
It is similar to Python's Construct 2.9 but it is language-agnostic. The format description is done in YAML-based .ksy format, which then can be compiled into a wide range of target languages.
