31
32 start file:
33         BLENDER_V100    12 bytes  (versie 1.00)
34                                         V = big endian, v = little endian
35                                         _ = 4 byte pointer, - = 8 byte pointer
36
37 datablocks:             also see struct BHead
38         <bh.code>                       4 chars
39         <bh.len>                        int,  len data after BHead
40         <bh.old>                        void,  old pointer
41         <bh.SDNAnr>                     int
42         <bh.nr>                         int, in case of array: amount of structs
43         data
44         ...
45         ...
46
47 Almost all data in Blender are structures. Each struct saved
48 gets a BHead header.  With BHead the struct can be linked again
49 and compared with StructDNA .

51 WRITE
52
53 Preferred writing order: (not really a must, but why would you do it random?)
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
