Magic numbers:

The header consists of 32 bytes as follows:
Size     Type Value                                         Description
9 bytes  char "Caligari "                                   Identifies Caligari file
6 bytes  char "V00.01"                                      Version number of file.  This document describes version 00.01 files
1 byte   char "A" for ASCII or "B" for binary               Specifies whether file is in ASCII format or binary format
2 bytes  char "LH" for little endian or "HL" for big endian Intel based machines are little endian and currently all Caligari files are too.
13 bytes char "             "                               Leave as blank spaces
1 byte   char "\n" Newline character                        Newline
