  *   RFC822 compliant, don't SEGV and try to return as much useful
  *   data as possible.
  *
+ * Define TAL_USE_TALLOC to use libtalloc as the allocator, otherwise

+ * it too).
+ *
  * Example:
+ *     // Outputs "body\n"

+ *     // Given "To" outputs <to@example.com>
  *     char buf[] = "From: <from@example.com>\n"
  *                  "To: <to@example.com>\n\n"
  *                   "body\n";
  *     struct rfc822_msg *msg;
- *     struct bytestring body;
+ *     struct bytestring out;
  *
  *     msg = rfc822_start(NULL, buf, sizeof(buf));
- *     body = rfc822_body(msg);
- *     fwrite(body.ptr, 1, body.len, stdout);
+ *     if (!argv[1])
