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.
