Guessing destination filenames wget-style has never been very robust, so require users to specify them. | var obj = process.ARGV[2];

Initialize the download. | var download = new get({

});
switch (dest) {
case '-': |
Download to disk. | download.asString(function(err, str) { |
Print both errors and debugging messages to stderr so that eventual piping is succesfull | if (err) {
sys.err(err);
} else {

default: |
