For --xed the xed tool is needed. Here is how to install it:

  $ git clone https://github.com/intelxed/mbuild.git mbuild
  $ git clone https://github.com/intelxed/xed
  $ cd xed
  $ ./mfile.py --share
  $ ./mfile.py examples
  $ sudo ./mfile.py --prefix=/usr/local install
  $ sudo ldconfig
  $ sudo cp obj/examples/xed /usr/local/bin

Basic xed testing:

  $ xed | head -3
