 Changes between 0.9.6 and 0.9.7  [xx XXX 2000]



  *) Enhance bctest to search for a working bc along $PATH and print

     it when found.

     [Tim Rice <tim@multitalents.net> via Richard Levitte]



  *) Add a 'copy_extensions' option to the 'ca' utility. This copies

     extensions from a certificate request to the certificate.
