QUERIES
  For most query values, the query type is inferred. However, some types of queries
  cannot be inferred and so the -t option must be used. The domain search by name
  (dsbyname) and entity search by name (esbyname) queries can take wildcards ('*'),
  but these must be quoted or escaped to avoid processing by the invoking OS shell
  on Unix-like operating systems.

CONFIGURATION
  When this program is run for the first time, it creates a directory called .NicInfo
  (on Unix style platforms) or NicInfo (on Windows) in the users home directory. The
  home directory is determined by the $HOME environment variable on Unix style platforms
  and $APPDATA on Windows.

  A configuration file is created in this directory called config.yaml. This is a YAML
  file and contains a means for specifying most of the features of this program (instead
  of needing to specify them on the command line as options). To set the configuration
  back to the installation defaults, use the --reset option. This maybe desirable when
  updating versions of this program.

  A directory called rdap_cache is also created inside this directory. It holds cached
  values from previously executed queries.

CACHING
  This program will write query responses to a cache. By default, answers are pulled
  from the cache if present. This can be turned on or off with the --cache option or
  using the cache/use_cache value in the configuration file.

  Expiration of items in the cache and eviction of items from the cache can also be
  controlled. The cache can be manually emptied using the --empty-cache option.

BOOTSTRAPPING
  Bootstrapping is the process of finding an appropriate RDAP server in which to send
  queries. This program has a three tier bootstrapping process.

  The first tier looks up the most appropriate server using internal tables compiled
  from IANA registries. If an appropriate server cannot be found, bootstrapping falls
  to the second tier.

  The second tier has a default server for each type of RDAP query (domain, ip, autnum,
  nameserver, and entity). If this program cannot determine the type of query, bootstrapping
  falls to the third tier.

  The third tier is a default server for all queries.

  All bootstrap URLs are specified in the configuration file. Bootstrapping maybe
  bypassed using the -b or --base option (or by setting the bootstrap/base_url in the
  configuration file).

USAGE FOR SCRIPTING
  For usage with shell scripting, there are a couple of useful command line switches.

  The --json option suppresses the human-readable output and instead emits the JSON
  returned by the server. When not writing to an output file, this options should be
  used with the -Q option to suppress the pager and program runtime messages so that
  the JSON maybe run through a JSON parser.

  The --jv option instructs this program to parse the JSON and emit specific JSON
  values.  This option is also useful in combination with the -Q option to feed the
  JSON values into other programs.  The syntax for specifying a JSON value is a
  list of JSON object member names or integers signifying JSON array indexes separated
  by a period, such as name1.name2.3.name4.5. For example, "entities.0.handle" would
  be useful for getting at the "handle" value from the following JSON:

    { "entities" : [ { "handle": "foo" } ] }

  Multiple --jv options may be specified.

DEMONSTRATION QUERIES
  There are several built-in demonstration queries that may be exercised to show the
  utility of RDAP. To use these queries, the --demo option must be used to populate
  the query answers into the cache. If the cache is already populated with items, it
  may be necessary to clean the cache using the --empty-cache option.

  When the --demo option is given, the list of demonstration queries will be printed
  out.
