Comment 3 for bug 1667502

Testing of tpm2-tools can be done by calling some of the binaries, even on uninitialized hardware:

$ /usr/sbin/tpm2_nvlist
1 NV indexes defined.

  0. NV Index: 0x1500015

 Hash algorithm(nameAlg):4
  The Index attributes(attributes):0x44040004
  The size of the data area(dataSize):4
   }

$ /usr/sbin/tpm2_listpcrs -s
