"""[[ This template demonstrates how to create a docstring for the PyNEST API.

   If you have modified an API, please ensure you update the docstring!

   The format is based on `NumPy style docstring
   <>`_ and uses
   reStructuredText markup. Please review the syntax rules if you are
   unfamiliar with either reStructuredText or NumPy style docstrings.

   Copy this file and replace the sample text with a description of the API.
   The double bracketed sections [[ ]], which provide explanations, should be
   completely removed from your final version - Including this entire

    [[ In a single 'summary line', state what the function does ]]
    [[ All functions should have a docstring with at least a summary line ]]

    [[ Below summary line (separated by new line), there should be an extended
       summary section that should be used to clarify functionality.]]

    Any combination of source, target, synapse_model and
    synapse_label parameters is permitted.

    [[ Deprecation warnings should appear directly after the extended summary.
      It should state in what version the object was deprecated, when it will
      be removed and what recommend way obtains the same functionality]]

            `ndobj_old` will be removed in NumPy 2.0.0, it is replaced by
            `ndobj_new` because the latter works also with array subclasses.

    heading ]]

        Source GIDs, only connections from these

    Details on the connectivity. [[ Here details regarding the code or further
    explanations can be included. This section may include mathematical
    equations, written in LaTeX format. You can include references to relevant
    papers using the reStructuredText syntax. Do not include model formulas ]]
