The text provided is a practical guide for producing ebooks with complex mathematics using a MathJax-based source HTML that is converted into a final HTML with SVG images. It explains when to use inline SVG or MathML, describes the m2svg tool and its command-line usage, and shows how TeX expressions delimited by display and inline markers are turned into <img> links with SVGs stored in an images directory. An example illustrates the conversion of a simple algebraic formula. The guide specifies the expected Project Gutenberg directory structure for the final and source files, then details the submission steps (including bundling the source HTML and a readme) and a thorough errata workflow: edit the source, regenerate SVGs, check errors and the browser preview, replace generated images while preserving non-generated ones, clean up temporary files, verify image usage, and re-upload the corrected package.
