Well, here is Sun's /bin/true:

#! /bin/sh
#
#	@(#)true.sh 1.5 88/02/07 SMI; from UCB
#
exit 0

Its revision number is 1.5.  This put me in a philosophical mood, so I
so I set out to find the original or absolute truth.  After much
speculation around here, here is the Top 5 List of what /bin/true used
to be...

1.4) exit
1.3) exit 1
1.2) 42
1.1) test !`/bin/false`

(drum roll)

1.0) echo true
