-cat <<'NOTE'
-
-Done. Still needs doing by hand:
-
-  * libs/DataTables -- rebuild the bundle at datatables.net/download with the
-    Bootstrap 5 styling option instead of Bootstrap 4. One call site
-    (js/app.js: new DataTable('.dataTables')), so only the CSS changes.
-
-  * libs/daterangepicker -- works under BS5 but styles itself against BS4
-    variables; check the popup against your theme.
-
-Unaffected and left alone: tinymce, clipboardjs, SortableJS, chart.js,
-fullcalendar, dropzone, intl-tel-input, inputmask, toastr, jquery, jquery-ui,
-moment, popper, select2, TCPDF, PHPMailer, stripe-php, htmlpurifier.
