define Package/samba4/Default/description
  The Samba software suite is a collection of programs that implements the
  SMB/CIFS protocol for UNIX systems, allowing you to serve files and printers.

  Samba 4 implements up-to protocol version SMB v3.1.1 (Win10), supports mDNS via AVAHI and a AD-DC setup via krb5.
  NOTE: No cluster and printer support.
