  A sketch of our results on CPT and strings is given. A mechanism for
spontaneous CPT violation in string theory is briefly reviewed, and recent
theoretical progress is summarized. Possible CPT-violating contributions to a
four-dimensional low-energy effective theory could produce effects at levels
testable in neutral-meson systems. Likely experimental signatures and
attainable bounds are outlined in candidate experiments with correlated and
uncorrelated neutral mesons.
