Curator is a Daemon which watches a directory and converts any books in the directory to .mobi files and places the converted books to another directory.
Also it can optionally send the converted books as an email. This can enable usecases where the books can be sent to Kindle email automatically.
This uses ebook-convertor tool from calibre. So calibre is expected to be installed.
