This will create a directory episodes/YYYYMMDDhh so you can't publish more than a podcast every hour using this command. The audio file inherits the directory name.
You can force a directory name with a parameter after the audio file.
this will create or update the `output_html` directory with your audio files, the RSS file, an index.html file listing all the episodes and the logo file if any.
My podcast feed is available at `https://perso.pw/lambda/feed.xml` which is on server `perso.pw` in `/var/www/htdocs/lambda/`.
I add new episodes with `potcasse episode "A made something nice" ~/Podcast/episodeXX/file.ogg` then I use `potcasse gen` that will refresh the directory `public_html` with metadata and episodes, finally I put it online with `rsync -av public_html/ perso.pw:/var/www/htdocs/lamda/`.
