+    (description
+     "This package provides information about the Euclid space telescope and
+survey that is needed to produce simulations using GalSim.  Some of the
+information provided is approximate, aimed towards fast simulations rather
+than full accuracy in representation of Euclid images.  Places where the
+information is only approximate are flagged and described in the docstring,
+and we particularly highlight that the PSF is only approximate; for details,
+see the docstring of the @code{getPSF()} method.  This library should enable
+generation of Euclid-like images of sufficient fidelity for preliminary
+exploration of object detection, photometry, deblending, and joint analysis
+with ground-based observatories.  For applications requiring high precision
+such as weak lensing, the higher fidelity simulations available within the
+Euclid Consortium should be used.")
