After a quick-and-dirty introduction to nonstandard analysis, we will
define the asymptotic cones of a metric space and we will play around
with nonstandard tools to show some results about them.
For example, we will hopefully prove that any separable asymptotic cone
is proper and we will classify real trees appearing as asymptotic cones
of groups.
