docs: Parse domain to employer stream.
  
          Each line of the stream has to contain a domain and a organization,
          or employer, separated by tabs. Comment lines start with the hash
          character (#)
  
          Example:
  
          # Domains from domains.txt
          example.org        Example
          example.com        Example
          bitergia.com       Bitergia
          libresoft.es       LibreSoft
