Use this command to upload a file using curl:
<pre>curl {{ request.route_url('files') }} -X PUT -F "file=@/path/to/your/file"</pre>

Use this form to upload a file! (TODO: Implement with jQuery, properly display results)
<form action="/files" method="PUT" accept-charset="utf-8" enctype="multipart/form-data">
<label for="file">File</label>
<input id="file" name="file" type="file" value="" />
<input type="submit" value="Upload!" />
</form>
<pre>curl -X PUT {{ request.route_url('files') }} -F "file=@/path/to/your/file"</pre>
You will get a JSON response containing a bunch of checksums and a <b>key</b>.
Take good care of it, as <b>the key it is your only way to delete the file later</b>!
In order to <b>delete</b> a file, use this curl command:
<pre>curl -X DELETE {{ request.route_url('files') }}/<i>uuid</i>/<i>key</i></pre>
