 The Samba software suite is a collection of programs that
 implements the SMB/CIFS protocol for unix systems, allowing you to serve
 files to Windows, NT, OS/2 and DOS clients. This protocol
 is sometimes also referred to as the LanManager or NetBIOS protocol.
 .
 These packages contain snapshot versions of Samba 4, the next-generation
 version of Samba. These should be considered _experimental_, and should
 not be used in production.
 .
 This package contains the common files that are used by both the server
 (provided in the samba package) and the client (provided in the samba-clients
 package).
