+convert_prealigned_text_to_readalong():
     convert a list of sentences into a readalong XML string ready to print to file.
     Just like align and make_xml, this function expects a black line (empty list) to
     make a paragraph break, and two consecutive blank lines to make a page break.
     Unlike the other functions here, this function is not a wrapper around the CLI and
-    it just returns the string, non status.

+convert_prealigned_text_to_offline_html():
+    same as convert_prealigned_text_to_readalong, but also creates an offline HTML file.
