+     "PyBDSF (the Python Blob Detection and Source Finder) is a tool designed
+to decompose radio interferometry images into sources and make available their
+properties for further use.  PyBDSF can decompose an image into a set of
+Gaussians, shapelets, or wavelets as well as calculate spectral indices and
+polarization properties of sources and measure the psf variation across an
+image.  PyBDSF uses an interactive environment based on CASA that will be
+familiar to most radio astronomers.  Additionally, PyBDSF may also be used in
+Python scripts.")
