-----------------
struct -- Interpret strings as packed binary data 
 
 
 This module performs conversions between Python values and C structs 
represented as Python strings. It uses format strings (explained below) as 
compact descriptions of the lay-out of the C structs and the intended 
conversion to/from Python values. This can be used in handling binary data 
stored in files or from network connections, among other sources.
