-Algorithmic correction of fisheye lens distortion
+Algorithmic correction of fisheye lens distortion, written in the style of a NetPBM graphics tool.
 
+It takes no command-line arguments, and reads the image from from stdin. As with NetPBM-style utilities, you will likely need to combine other utilities to convert to/from the ppm format or do any additional image processing steps that you require.
