The Magellan engine comprises a set of folders and files that are required to make a Magellan site work. These are added to your system as part of the Magellan installation, typically in Program Files. Author-it copies all these folders and files to the publish folder when you publish a Magellan book.
The installed Magellan engine folders and files provide the default site look and feel and operation. If you want to customize your site, for example, to use different colors, icons, table style, decide how the Table of Contents shows on site opening, etc., define a specific Magellan theme for each different look you require and add any of the customized files described in this section. You are prompted to choose the theme on book publish, and Author-it uses the theme files to extend or override the Magellan engine file.
