Detailed Documentation
**********************
Exec shell commands and reuse the output
========================================
This recipe is for execute shell commands and get the output in another part of
the buildout. The commands are defined in a section called commands, one per
line and the output can be referenced from other parts using the ${...} syntax.
>>> write('dummy.py',
... '''
... class Recipe(object):
...
... def __init__(self, buildout, name, options):
... self.options = options
...
... def install(self):
... if 'output_1' in self.options:
... print self.options['output_1']
... if 'output_2' in self.options:
... print self.options['output_2']
... return ()
...
... def update(self):
... pass
... ''')
>>> write('setup.py',
... '''
... from setuptools import setup
...
... setup(name='dummyrecipe',
... entry_points = {'zc.buildout': ['default = dummy:Recipe']})
... ''')
>>> write('buildout.cfg',

... ''')
>>> print system(join('bin', 'buildout')),

ECHO
The shell says: hello.
If we give an empty command we get a hint.
