     3  """This sub-package provides text substitution services for creating C++ functions.
     4
     5  The helper classes in this package are meant to be used by the actual
     6  calldef code creators (that are not part of this sub-package). They
     7  implement the core of the "arg policy" mechanism which can be used by
     8  a user to modify the source code for a function.
     9
    10  The main class of this sub-package is the class L{substitution_manager_t}. This
    11  class maintains two sets of special variables, one for the wrapper function
    12  and one for the virtual function, and provides text substitution services.
    13  The variables contain parts of source code that can be inserted into the
    14  function source code template which is generated by the user of the class.
