I have all the felix related git projects checked out next to one another.

Base dot-htaccess-cms construction

This is generated in felix-site-pub last-cms branch using

Auto-editing to current page locations, and missing locations

This is done using the highly-experimental htaccess-edit-extension Antora extension. To run, copy package.json-htaccess-edit to package.json and run npm clean-install and npm run build-htaccess. This will generate dot-htaccess-current and dot-htaccess-legacy.

Final .htaccess file assembly

The build will generate a base .htaccess file from the start page and page aliases in the .adoc source. Some shell commands will append dot-htaccess-current, dot-htaccess-legacy, and dot-htaccess-static to produce the final file.
