        What is cp.recipe.cmd ?
        =======================
        
        This recipe is used to run one or more command lines.
        
        I stole this from iw.recipe.cmd (http://pypi.python.org/pypi/iw.recipe.cmd/0.1)
        
        It works differently tho, when it comes to executing shell commands.  iw.recipe.cmd would push each command out separately in it's own shell.  Here I push them out to a shell script, and then run the shell script.  This way things like CD and other things that require state within the shell work great.
        
        Also, I changed the way it works in the config file.
        we have 2 options in the command.
        
        [commandexample]
        recipe = cp.recipe.cmd
        install_cmds =
           echo "install commands go here"
        	cd /tmp
        	echo `pwd`
        	echo 'see, I exist in one shell instance.'
        update_cmds =
        	echo "update commands go here"
        	
        
        On install, install_cmds will be turned into a shell script, and then ran.
        on update, update_cmds will be turned into a shell script and then ran.  If you want update_cmds to be the same you can do something like this:
        update_cmds = ${commandexample:install_cmd}
        
        (where commandexample is the name of your part)
        
        python code execution is unchanged in this version, and below are the original docs.
        
        
        We need a config file::
        
          >>> cfg = """
          ... [buildout]
          ... parts = cmds
          ...
          ... [cmds]
          ... recipe = iw.recipe.cmd
          ... on_install=true
          ... cmds= %s
          ... """
        
          >>> test_file = join(sample_buildout, 'test.txt')
          >>> cmds = 'touch %s' % test_file
          >>> write(sample_buildout, 'buildout.cfg', cfg % cmds)
        
        Ok, so now we can touch a file for testing::
        
          >>> print system(buildout)
          Installing cmds.
        
          >>> 'test.txt' in os.listdir(sample_buildout)
          True
        
        And remove it::
        
          >>> test_file = join(sample_buildout, 'test.txt')
          >>> cmds = 'rm -f %s' % test_file
          >>> write(sample_buildout, 'buildout.cfg', cfg % cmds)
        
          >>> print system(buildout)
          Uninstalling cmds.
          Installing cmds.
        
          >>> 'test.txt' in os.listdir(sample_buildout)
          False
        
        We can run more than one commands::
        
          >>> cmds = '''
          ... touch %s
          ... rm -f %s
          ... ''' % (test_file, test_file)
        
          >>> test_file = join(sample_buildout, 'test.txt')
          >>> cmds = 'rm -f %s' % test_file
          >>> write(sample_buildout, 'buildout.cfg', cfg % cmds)
        
          >>> print system(buildout)
          Updating cmds.
        
          >>> 'test.txt' in os.listdir(sample_buildout)
          False
        
        We can also run some python code::
        
          >>> cfg = """
          ... [buildout]
          ... parts = py py2
          ...
          ... [py]
          ... recipe = iw.recipe.cmd:py
          ... on_install=true
          ... cmds= 
          ...   >>> sample_buildout = buildout.get('directory', '.')
          ...   >>> print os.listdir(sample_buildout)
          ...   >>> shutil.rmtree(os.path.join(sample_buildout, "bin"))
          ...   >>> print os.listdir(sample_buildout)
          ... [py2]
          ... recipe = iw.recipe.cmd:py
          ... on_install=true
          ... cmds=
          ...   >>> def myfunc(value):
          ...   ...     return value and True or False
          ...   >>> v = 20
          ...   >>> print myfunc(v)
          ... """
        
          >>> write(sample_buildout, 'buildout.cfg', cfg)
        
        Ok, so now we run it::
        
          >>> print system(buildout)
          Uninstalling cmds.
          Installing py.
          ['.installed.cfg', 'bin', 'buildout.cfg', 'develop-eggs', 'eggs', 'parts']
          ['.installed.cfg', 'buildout.cfg', 'develop-eggs', 'eggs', 'parts']
          Installing py2.
          True
