  - you won't be able to use mercurial repositories unless you install the hg command on your system.
  - you won't be able to use darcs repositories unless you install the darcs command on your system.

This development version of opam requires an update to the layout of /home/opam/.opam from version 2.0 to version 2.2~alpha, which can't be reverted.
You may want to back it up before going further.

   Quick setup for VIM
   -------------------
   Append this to your .vimrc to add merlin to vim's runtime-path:
     let g:opamshare = substitute(system('opam var share'),'\n$','','''')
     execute "set rtp+=" . g:opamshare . "/merlin/vim"

   Also run the following line in vim to index the documentation:
     :execute "helptags " . g:opamshare . "/merlin/vim/doc"

   Quick setup for EMACS
   -------------------
   Add opam emacs directory to your load-path by appending this to your .emacs:

<><> Handling external dependencies <><><><><><><><><><><><><><><><><><><><><><>

opam believes some required external dependencies are missing. opam can:
> 1. Run apt-get to install them (may need root/sudo access)
  2. Display the recommended apt-get command and wait while you run it manually (e.g. in another terminal)
  3. Continue anyway, and, upon success, permanently register that this external dependency is present, but not detectable
  4. Abort the installation
