Description and Notes

This module is a module that rises to the level of the short list of essential module that every Drupal website builder should deploy on their site by default. The node clone module provides a simple button so that when adding multiple modules to a website, rather than starting from scratch for each node with an empty form, the form is prepopulated with the contents of an existing (previous) node, onto which only the changed settings need to be modified. This is truly handy. 

This is currently only a development release version. However, the develop branch version has been working properly/nominally.
