Ok I am still confused

svn.freebsd.org has for example ( if I got this correct )

base/head    - CURRENT-12
base/stable/11    - STABLE-11
base/releng/10.1    - ?
base/release/10.1.0    - ?

Which one would have  FreeBSD 10.1-RELEASE-p35 or later?

I got the part on how to use svnlite to fetch the source, I just don't 
know which one is what

I want to update

  uname -a FreeBSD 10.1-RELEASE-p35 #0 net:/usr/obj/usr/src/sys/GENERIC  
amd64

Thanks
