  Plumbum Shell Combinators
  -------------------------
  A wrist-handy library for writing shell-like scripts in Python, that can serve 
  as a ``Popen`` replacement, and much more::
  
      >>> from plumbum.cmd import ls, grep, wc, cat
      >>> ls()
      u'build.py\ndist\ndocs\nLICENSE\nplumbum\nREADME.rst\nsetup.py\ntests\ntodo.txt\n'
      >>> chain = ls["-a"] | grep["-v", "py"] | wc["-l"]
      >>> print chain
      /bin/ls -a | /bin/grep -v py | /usr/bin/wc -l
      >>> chain()
      u'12\n'
      >>> ((ls["-a"] | grep["-v", "py"]) > "/tmp/foo.txt")()
      u''
      >>> ((cat < "/tmp/foo.txt") | wc["-l"])()
      u'12\n'
      >>> from plumbum import local, FG, BG
      >>> with local.cwd("/tmp"):
      ...     (ls | wc["-l"]) & FG
      ... 
      13              # printed directly to the interpreter's stdout
      >>> (ls | wc["-l"]) & BG
      <Future ['/usr/bin/wc', '-l'] (running)>
      >>> f=_
      >>> f.stdout    # will wait for the process to terminate
      u'9\n'
  
  Plumbum includes local/remote path abstraction, working directory and environment 
  manipulation, process execution, remote process execution over SSH, tunneling, 
  SCP-based upload/download, and a {arg|opt}parse replacement for the easy creation 
  of command-line interface (CLI) programs.
