"""Function binding conditions can be specified manually by supplying a versions
array instead of the names array. Each version has the following keys:
name: Mandatory. Name of the function. Multiple versions can have the same
name but different conditions.
extensions: Extra Extensions for which the function is bound. Only needed
in some cases where the extension cannot be parsed from the
headers.
By default, the function gets its name from the first name in its names or
versions array. This can be overridden by supplying a 'known_as' key.
