This may not be totally accurate. Upon reflection, it dawns on me
that the CrackLib library may also check for re-used passwords and
passwords too similar to the previous one. However, these are not
"password policies cracklib likes". This is the default functionality
of the CrackLib library.

I have not looked at the source code for the fascistcheck function
(which provides most of CrackLib's password checking ability), so
there very well may be other things it checks to ensure that the
password a user selects is "secure".
