I think it was stated pretty clearly in this thread.
I myself use the export script feature to change custom code into php pages with extension changes, links, etc and test with a mysql database using XAMPP. This integrates my CMS (uses PHP) and allows for complete editing of the files with Sublime Text inside Bootstrap Studio. The export method I use is a html parser called Python Beautiful Soup. Allows complete control over the document and what is contained in it and writes, overwrites, deletes old html file, create folders, new extensions etc.
