Sub-vendoring
-------------

The following libraries are vendored in "vendored" directory:

    github.com/camlistore/go4/lock
    github.com/cznic/exp/lldb

Both are unstable and recommended for vendoring hence they are not feasible
to ship in their own standalone packages. See more in

  https://github.com/camlistore/go4#details
  https://github.com/cznic/exp
  https://github.com/cznic/ql/issues/122
