3.2.3. `INCBIN': Including External Binary Files
------------------------------------------------
`INCBIN' is borrowed from the old Amiga assembler DevPac: it includes
a binary file verbatim into the output file. This can be handy for (for
example) including graphics and sound data directly into a game
executable file. It can be called in one of these three ways:
incbin "file.dat" ; include the whole file
incbin "file.dat",1024 ; skip the first 1024 bytes
incbin "file.dat",1024,512 ; skip the first 1024, and
; actually include at most 512
