+<p>With this option, <b>pgmhist</b> works on images that contain invalid gray
+values.  Normally, like most Netpbm programs, <b>pgmhist</b> fails if it
+encounters a gray value greater than the maxval that the image declares.  The
+presence of such a value means the image is invalid, so the pixels have no
+meaning.  But with <b>-forensic</b>, <b>pgmhist</b> produces a histogram
+of the actual gray values without regard to maxval.  It issues messages
+summarizing the invalid pixels if there are any.
+
+<p>One use for this is to diagnose the problem that caused the invalid Netpbm
+image to exist.
+
+<p>There is a small exception to the ability of <b>pgmhist</b> to process
+invalid pixels even with <b>-forensic</b>: it can never process a gray value

+possible for a number greater than that to appear where a gray value belongs.
