New Revision: 324114
URL: https://svnweb.freebsd.org/changeset/base/324114

Log:
  Update cpucontrol(8).
  
  Mention new -n flag.
  Remove optional -h from the operation list lines, -h would cause the
  utility to exit without performing the action.
  Explain the default path behavior, list default path.
  Correct example of update performed from the non-default path,
  it needs -n and the trailing slash is redundand.
  Remove useless BUGS section.
