 Some of the integers in this structure are stored in Big Endian. This is
 denoted with "(BE)".
 
-Unfortunately, toxcore copies the friend structure directly from memory to the
-state file. This makes the state format platform dependent because the way a
-structure is laid out in memory differs across platforms and compilers. A
-common layout of this structure in memory (GCC on x86 and x86\_64) is described
-below and should be accounted for both when serializing and deserializing the
-state file.
