 ## afs_rebuild.csv
-**afs_rebuild.csv** contains entries describing how to pack '''root''' files in the AFS. All offsets and indexes values are stored in hexadecimal with **0x** prefix: 0xabcdef. Use **auto** value for offsets or indexes when it's possible. Offsets have to be aligned to 0x800 (2048). Put one line per selected file that you wan't to constraint using the format: "unpacked_filename/index/offset/packed_filename", for instance: "dummy (5).bin/0x12/0x80000/dummy.bin". You can put auto to index or offset: "dummy (5).bin/auto/auto/dummy.bin". For an empty block add only offset/length couple with values aligned to 0x800, for instance: "0x80000/0x5000".

 When rebuilding, remove all files without constraints from '''afs_rebuild.csv'''. Then put '''auto''' value in indexes and offsets that doesn't have constraints. While rebuilding the AFS filename_resolver.csv will be removed but you can keep changes about filenames by adding entries with unpacked_filename+index (and packed_filename when there is a FD) into this file.
