+A little program I wrote can be used to analyze the quality of the math
+library implementation. It simply computes the real result with a high
+precision and determines from this the error of the value the libm
+implementation produced. Very easy.
+To make the time waiting for the result a bit more interesting the program
+displays the error graphically in an updated window. Once the program is
+done it writes the plot in a GIF file which then can be used for later
+reference.
