Run a WoT Servient in the current directory.
If no SCRIPT is given, all .js files in the current directory are loaded.
If one or more SCRIPT is given, these files are loaded instead of the directory.
If the file 'wot-servient.conf.json' exists, that configuration is applied.

Options:
  -v,  --version                   display node-wot version
