'''The @text node is for embedding text files in a leo node that won't be saved with the leo file, and won't contain any sentinel leo comments. Children of @text nodes are not saved with the derived file, though they will stay in the outline. When a outline is first loaded any @text nodes are filled with the contents of the text files on disk. To refresh the contents of an @text node, double click on the heading icon.
