 node-calibre is mostly a simple wrapper around Calibre's CLI using Node's [child_process.exec()](https://nodejs.org/api/child_process.html), without many extra features added. In the future this package will contain more methods unique to each of Calibre's binaries and with both better error checking and improved results provided on success.
