The PrettyPrintCrl class is a utility program designed to "pretty print"
a CRL. It assumes that the name of a data file is passed to the
program via the command line, and that the contents contain a CRL
encoded in an ASCII BASE 64 format. Note that the data file may contain
an optional "-----BEGIN" header and/or an optional "-----END" trailer.
The program may be invoked as follows:
PrettyPrintCrl <input filename> [output filename]
NOTE: <input filename> must contain an ASCII
BASE 64 encoded CRL
<output filename> contains a CRL displayed
in a "pretty print" ASCII format
