Embed in topics: Selecting this option integrates the JavaScript into each topic. An external JavaScript file is not generated. Embedding JavaScript files ensures greater compatibility with older browsers, however, it increases the size of your HTML files.
Limit file size to 32k: Some older browsers do not support external JavaScript files that are larger than 32k. Selecting this option forces the creation of multiple, smaller JavaScript files (each no larger than 32k). This option ensures greater compatibility with older browsers, but results in the creation of extra files.
