/**
 * Example showing how to upload a file to a ftp server and rename it right after.
 * Mostly based on https://curl.haxx.se/libcurl/c/ftpupload.html
 * How to run:
 *  node examples/16-ftp-full-upload.js ftp://example-of-ftp-host.com username password
 * To test you can use ftp://speedtest.tele2.net:
 *  node examples/16-ftp-full-upload.js ftp://speedtest.tele2.net/upload anonymous
 * Keep in mind the speedtest server does not accept file renaming, so it will fail on the quote command
