"Format is:

1. Magic number (3 Bytes):

3. Game version (1 Byte)
4. Cell size (1 Byte)
5. Width, in cells (1 Bytes)
6. Heigth, in cells (1 Bytes)
7. Unzipped size of the save data (4 Bytes)
8. Save data, zipped with bzip2:


1. All walls (1 Byte each)
2. For FANs: X speed (1 Byte each)
3. For FANs: Y speed (1 Byte each)
4. All particles, types (1 Byte each)

1. X position (2 Bytes)
2. Y position (2 Bytes)
3. Text align (1 Byte)
4. Length of text (1 Byte)
5. Text (IV Bytes)


EOF"

Since the EOF is indicated as part of the format I assume I need to signal the EOF (end of file) withing the file itself. How do I signal an EOF in TPT stamp format?
