We present here an overview of PulsarSpectrum, a program that simulates the
gamma ray emission from pulsars. This simulator reproduces not only the basic
features of the observed gamma ray pulsars, but it can also simulate more
detailed effects related to pulsar timing. It is a very useful tool to
understand the GLAST capabilities in the pulsar science.Comment: 6 pages, 3 figures, contribution for "Third Workshop on Science with
