# The (false match) message is to correct that behavior.  Perhaps it is

# 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.
