    Create a symbolic link pointing to *source* named *link_name*.
 
-   On Windows, symlink version takes an additional, optional parameter,
-   *target_is_directory*, which defaults to False.

-   symlink(source, link_name, target_is_directory=False)
+   On Windows, a symlink represents a file or a directory, and does not morph to
+   the target dynamically.  For this reason, when creating a symlink on Windows,
+   if the target is not already present, the symlink will default to being a
+   file symlink.  If *target_is_directory* is set to ``True``, the symlink will
+   be created as a directory symlink.  This parameter is ignored if the target
+   exists (and the symlink is created with the same type as the target).
