-  """Generate an output from one or several input and a template.
-  
-  Take "input-list" buildout parameter as input.
-  Each input of the list is separated by \n
-  Each input contains :
-    1/ The parameter to use (like mybuildoutpart:myparameter)
-    2/ The name of the input to use as key.
-
-  If all parameters in input are found, create an "output" parameter from a
-  "template" parameter. The "template" parameter is just a string containing
-  python parameters (like %(mykey)s).
-
-  Will produce nothing if one element of "input_list" doesn't exist.
-  Will raise if any input reference non-existent buildout part.
-
-  Example : 
-  [get-output]
-  recipe = slapos.cookbook:generate_output_if_input_not_null
-  input-list =
-    firstkey mybuildoutpart:myparameter
-    otherkey myotherbuildoutpart:myotherparameter
-  template = I want to get %(key)s and %(otherkey)s
-
-  This example will produce an "output" parameter if myparameter and
-  myotherparameter are defined.
