  * === added directory usr/lib/byobu/include, experimental/byobu-
    classroom, usr/bin/byobu, usr/bin/byobu-ctrl-a, usr/bin/byobu-
    disable, usr/bin/byobu-enable, usr/bin/byobu-export, usr/bin/byobu-
    janitor, usr/bin/byobu-launch, usr/bin/byobu-launcher,
    usr/bin/byobu-launcher-install, usr/bin/byobu-launcher-uninstall,
    usr/bin/byobu-quiet, usr/bin/byobu-reconnect-sockets, usr/bin/byobu-
    select-backend, usr/bin/byobu-select-profile, usr/bin/byobu-shell,
    usr/bin/byobu-silent, usr/bin/byobu-status, usr/bin/byobu-status-
    detail, usr/bin/byobu-ugraph, usr/bin/byobu-ulevel,
    usr/lib/byobu/.common => usr/lib/byobu/include/common (properties
    changed: -x to +x), usr/lib/byobu/.constants =>
    usr/lib/byobu/include/constants, usr/lib/byobu/.dirs =>
    usr/lib/byobu/include/dirs, usr/lib/byobu/Makefile.am,
    usr/lib/byobu/notify_osd, usr/lib/byobu/.notify_osd =>
    usr/lib/byobu/include/notify_osd, usr/lib/byobu/.shutil =>
    usr/lib/byobu/include/shutil, configure.ac, Makefile.am,
    usr/lib/byobu/include/Makefile.am:
    - LP: #833768
    - move dotfiles out of usr/lib/byobu and into usr/lib/byobu/include
    - this was triggering some chrootkit warnings
  * usr/share/doc/byobu/help.tmux.txt:
    - reorder some documentation
  * usr/bin/byobu-launcher-install:
    - close LP: #854764, which was recently fixed
  * usr/bin/byobu-config: LP: #888247
    - deprecate the keybinding set selection from the config menu
    - no additional keybindg sets ever showed up, so this option
      is not worth having
    - deprecate background/foreground color selection; once, this was a
      primary feature of byobu :-)  It's not really any more;  it's
      trivial to change these in ~/.byobu/color now
    - deprecate window management from byobu-config; hard to get this
      right for both screen and tmux;  and I don't perceive that this
      is any longer one of byobu's main features (?)
    - standardize title formatting
    - clean up some whitespace and text
  * usr/bin/byobu-config, usr/share/doc/byobu/help.tmux.txt,
    usr/share/doc/byobu/help.txt => usr/share/doc/byobu/help.screen.txt,
    usr/share/doc/byobu/Makefile.am:
    - show tmux help in tmux, screen help in screen
  * experimental/byobu-classroom, usr/bin/byobu-ctrl-a, usr/bin/byobu-
    enable, usr/bin/byobu-select-backend, usr/bin/byobu-select-profile,
    usr/bin/byobu-ulevel, usr/lib/byobu/custom, usr/lib/byobu/disk,
    usr/share/byobu/tests/byobu-time-notifications: LP: #882814
    - use printf instead of "echo -n" for portability to Mac OSX
  * experimental/byobu-classroom: LP: #882813
    - fix minor use $SED
  * usr/bin/byobu-ctrl-a, usr/bin/byobu-janitor: LP: #882435
    - use BYOBU_PREFIX in a couple of places to allow better portability
