Each file represent a chapter in the resulting ePub. 26 | They are processed by name order, and will appear correspondingly in the e-book. 27 | 28 | * An `images` folder, containing the images to be included. Only GIF (`.gif` 29 | extension), JPEG (`.jpg` or `.jpeg` extensions), and PNG (`.png` extension) 30 | files are currently supported. This folder is *not* processed recursively, so 31 | all images should be placed at the root of this folder. 32 | 33 | * A `css` folder, containing the CSS files. This folder is *not* processed 34 | recursively, so all css files should be placed at the root of this folder. 35 | 36 | * A `description.json` containing meta-information about the e-book. The key 37 | `cover_image` should indicate the name of the cover image. 38 | The key `default_css` is a list of css file names that are applied by default 39 | on all chapters. 40 | The key `chapters` is a list of dictionaries, each one containing a key `markdown` 41 | indicating the name of the corresponding markdown file, and a key `css` indicating 42 | the name of the css file that should be applied specifically to this chapter. 43 | See the example in the repository for a typical `description.json` file. 44 | 45 | ## Limitations/Features to be addressed 46 | 47 | * Robustness checks in the `mark2epub.py` script 48 | * Recursive processing of the `images` and `css` folders 49 | * Support for additional fonts 50 | * Support for mathematical notation 51 |
