``Very close'' was my intent.

Their installer detects batch files and programs invoked from
AUTOEXEC.BAT, and asks the user whether or not to invoke them.  It
also examines all batch files that are CALLed or invoked directly,
because they might CALL or invoke others.  It then prepares a modified
AUTOEXEC.BAT (not before it backs up the original), and reboots.  The
modified AUTOEXEC.BAT invokes a program at the end which analyses the
results and does whatever is appropriate, which is either tell the
user "You are done" and ask them whether they want to accept the last
configuration, or change AUTOEXEC.BAT some more and reboot again.

From my experience, their rate of failure is very low, although they
turn on features that can be quite dangerous.  That's my idea of
``darn close''.
