+ * Example code that uploads a file name 'foo' to a remote script that accepts
+ * "HTML form based" (as described in RFC1738) uploads using HTTP POST.
+ *
+ * The imaginary form we'll fill in looks like:
+ *
+ * <form method="post" enctype="multipart/form-data" action="examplepost.cgi">
+ * Enter file: <input type="file" name="sendfile" size="40">
+ * Enter file name: <input type="text" name="filename" size="30">
+ * <input type="submit" value="send" name="submit">
+ * </form>
+ *
+ * This exact source code has not been verified to work.
