[Samba] samba-tool question

[lux-integ]

Greetings,

I compile samba 4.0.9 and 4.1.0 on a computer with these:-
--cpu -amd64 3 cres
--os blfs linux 64 bit gcc-4.8.1 linux-3.10.17 glibc-2.17

I have followed the samba4 wikis  where most refer to a samna-tool (am 
adminstrative tool  I presumed   in the ~/bin (or  ~/sbin) directory of   the 
samba4 install prefix.  I did an ls for  in the bin and sbin directories  of 
the samba4 installations  ( see below )

#---------------------------------------
linteg [ /usr  ]# ls bin/samba*
bin/samba-regedit
linteg [ /usr  ]# ls bin/smb*
bin/smbcacls   bin/smbclient4  bin/smbcquotas  bin/smbpasswd  bin/smbstatus   
bin/smbtar      bin/smbtree
bin/smbclient  bin/smbcontrol  bin/smbget      bin/smbspool   bin/smbta-util  
bin/smbtorture
linteg [ /usr  ]# 

#---------------------------------------

and I cannot find samba-tool. I also did a search of the installation prefix 
without avail.  
BUT when  I did a search of the samba build-tree I found a python-script of 
the name 'samba-tool' (which clearly was not installed ).

I would accordinglly like to know the following:-

--A --have I made a mistake in my compilation and installation of 
samba-{4.1.0/4.0.9} -and if so what is it ?  OR
--B-- is samba-tool now redundant   and the samba4-wikiis  out of date ?
--C-- whatever ?

advice will be appreciated.

sincerely
