Changes between 0.9.4 and 0.9.5 [xx XXX 2000]
+ *) Reorganise password command line arguments: now passwords can be
+ obtained from various sources. Delete the PEM_cb function and make
+ it the default behaviour: i.e. if the callback is NULL and the
+ usrdata argument is not NULL interpret it as a null terminated pass
+ phrase. If usrdata and the callback are NULL then the pass phrase
+ is prompted for as usual.

*) Add support for the Compaq Atalla crypto accelerator. If it is installed,
the support is automatically enabled. The resulting binaries will
autodetect the card and use it if present.
