Recent changes:
Version 1.9: Fix the URL associated with the 'Web Page' menu option.

Version 1.8: Fixed the logic that intends prevent the input and output files from being the same file. Under rare circumstances if the input and output pathnames were different but actually named the same file, the input file was truncated during the signing operation. The fix attempts to detect and disallow this case.
