Hi, earlier I created it as a wrapper using calibre and percollate. It was not portable at all.
This weekend, re-wrote it in golang to use go-readability for converting HTML to readable content and then build epub from there.
Now, binary can be used directly without worrying about extra dependencies.
Name is kindle-send but it is just pushing epubs via email. So shouldn't be a problem if you're using a different reader that supports receiving ebooks via email.
