NAME
       tpm_nvrelease

SYNOPSIS
       tpm_nvrelease [OPTIONS]

DESCRIPTION
       tpm_nvrelease releases an NVRAM area. The user must provide the index
       of the NVRAM area. If owner authentication is required then the user
       must provide the	owner password.

       Note that some areas cannot be released since they are permanent.
       Others can be release only after	a reboot of the	system.

       The following options are supported:

       -h, --help
	   Display command usage info.

       -v, --version
	   Display command version info.

       -l, --log [none|error|info|debug]

	   The owner password.

	   A   password	  may  be  directly  provided  for  example  by	 using
	   '--pwdo=password' or	'-opassword'. If no password is	provided  with
	   this	option then the	program	will prompt the	user for the password.
