MORE INFO
        You need "festival", "festival_client", "sox" programs on your Whatever/Linux install.
        The sox-plugins-freeworld package might be needed for the mp3 support.
        In order to use the festival's text-to-speech function you need to run it as a server
        with "festival --server".
        Also don't forget to configure the voice you want to use in festival.
        You can customize the main.js and main.html files in the project folder but run "go generate"
        and rebuild the executable afterwards to set up the new code.
        The file expansions.txt file contains regex rules for emoticons and their translations
        and the acronyms.txt file contains translations of acronyms.
        Both can be edited to remove or add new rules, but as previously said,
        you need to run "go generate" and rebuild the binary afterwards.
