Allows editing of model content fields (non relational) using your favorite text editor. Works kind of like VCS commits when they need a message. It fetches the models you select, serializes the objects into a temporary text file, and then loads that file with a specified text editor (eg vi,nano,emacs). Once you are done editing, quit the text editor and the changes are committed to your database. Very quick and easy way to update content without going into the admin. I use it to get around the WYSIWYG editor in the admin.
