Webnail reduces images so that they just fit within a bounding box
whose size is given in pixels or creates a web page that allows a
series of images to be displayed.  Documentation consists of a man page
and Javadoc files (in the javadocs subdirectory of this directory),
plus an on-line manual visible when the GUI is used.

When run with no arguments, a GUI will be used for input. Otherwise
the program uses a command-line interface.
