+@item @code{-ignore-version}
+@*Specify this to ignore the JTAG version field in the @code{-expected-id}
+option. When vendors put out multiple versions of a chip, or use the same
+JTAG-level ID for several largely-compatible chips, it may be more practical
+to ignore the version field than to update config files to handle all of
+the various chip IDs.
