  ; Valid values:

  ; You may override default_level by assigning a logging level

  ;
  ; Run:
  ;   nfd --modules
  ;   nrd --modules

  ; Or look for NFD_LOG_INIT(<module name>) statements in .cpp files

  ;   ; This section defines the trust model for NFD RIB Management. It consists of rules and

  ;   ;
  ;   ;     man ndn-validator.conf
  ;   ;
  ;   ; A trust-anchor is a pre-trusted certificate.  This can be any certificate that is the
  ;   ; root of certification chain (e.g., NDN testbed root certificate) or an existing
  ;   ; default system certificate `default.ndncert`.
  ;   ;
  ;   ; A rule defines conditions a valid packet MUST have. A packet must satisfy one of the
  ;   ; rules defined here. A rule can be broken into two parts: matching & checking. A packet
  ;   ; will be matched against rules from the first to the last until a matched rule is
  ;   ; encountered. The matched rule will be used to check the packet. If a packet does not
  ;   ; match any rule, it will be treated as invalid.  The matching part of a rule consists
  ;   ; of `for` and `filter` sections. They collectively define which packets can be checked
  ;   ; with this rule. `for` defines packet type (data or interest) and `filter` defines
  ;   ; conditions on other properties of a packet. Right now, you can only define conditions
  ;   ; on packet name, and you can only specify ONLY ONE filter for packet name.  The
  ;   ; checking part of a rule consists of `checker`, which defines the conditions that a
  ;   ; VALID packet MUST have. See comments in checker section for more details.
