/* This was set by JHT in liaison with Jeremy Allison early 1997
 * History:
 * Version 4.0 - never made public
 * Version 4.10 - New to 1.9.16p2, lost in space 1.9.16p3 to 1.9.16p9
 *              - Reappeared in 1.9.16p11 with fixed smbd services
 * Version 4.20 - To indicate that nmbd and browsing now works better
 * Version 4.50 - Set at release of samba-2.2.0 by JHT
 *
 *  Note: In the presence of NT4.X do not set above 4.9
 *        Setting this above 4.9 can have undesired side-effects.
 *        This may change again in Samba-3.0 after further testing. JHT
