The command requires a name prefix, which it uses to name the files in which 
it stores the generated keys. If you supply a -k or --keydir flag, it puts files 
in that directory; otherwise, it puts them in the working directory. For example,

dpcclient genKey myDPCKey -k keys 

creates two files, myDPCKey-private.pem and myDPC-public.pem, in the 'keys'
directory.`,
