47 Almost all data in Blender are structures. Each struct saved
48 gets a BHead header.  With BHead the struct can be linked again

54 Any case: direct data is ALWAYS after the lib block
55
56 (Local file data)
57 - for each LibBlock
58         - write LibBlock
59         - write associated direct data
60 (External file data)
61 - per library
62         - write library block
63         - per LibBlock
64                 - write the ID of LibBlock
65 - write FileGlobal (some global vars)
66 - write SDNA
67 - write USER if filename is ~/.B.blend
