+     "This package provides an astronomical image processing tool - SIRIL.  It is
+specially tailored for noise reduction and improving the signal/noise ratio of
+an image from multiple captures, as required in astronomy.  SIRIL can align
+automatically or manually, stack and enhance pictures from various file formats,
+even image sequence files (films and SER files).  It works well with limited
+system resources, like in embedded platforms, but is also very fast when run on
+more powerful computers and provides conversion to FITS from a large number of
+image formats.")
