# TADS (Text Adventure Development System)
#  All files are machine-independent (games compile to byte-code) and are tagged
#  with a version string of the form "V2.<digit>.<digit>\0" (but TADS 3 is
#  on the way).
#  Game files start with "TADS2 bin\n\r\032\0" then the compiler version.

#  Some saved game files start with "TADS2 save/g\n\r\032\0", a little-endian
#  2-byte length N, the N-char name of the game file *without* a NUL (darn!),
# "TADS2 save\n\r\032\0" and the interpreter version.
