-Usage: mib2rb [OPTION]... ROOT_NODE [ERB_FILE]
-
-Description
-  Prints a mib subtree according to the ERB_FILE.
-  Within the ERB file, the `root` variable contains the
-  Net::SNMP::Node object corresponding to ROOT_NODE, and
-  `nodes` is a collection of the root & all descendants.
-
-Options
-  -h,          Prints this usage information.
-
-               Aliases:   --help
-
-  -l LEVEL     Set the log level.
-               Logs are piped to STDERR, so you can redirect
-               STDOUT to a file without worrying about logs
-               getting into the output.
-
-               Values:   debug, info, warn, error, fatal, none
-               Default:  none
-               Aliases:  --log-level
-
-  -f FORMAT    Select the output format.
-               If this option is supplied with an ERB file,
-               the option is ignored and the file is used instead.
-
-               Values:   [d]efault, [j]son
-               Default:  default
-               Aliases:  --format
-
-Arguments
-  ROOT_NODE    [Required] The root node of the mib tree to translate.
-               May be specified as numeric oid or mib name.
-
-  ERB_FILE     [Optional] The template file to use for output.
-
-               Default:  Builtin template specifying human readable output.
-                         (See below)
