WARNING!

any2djvu uses an external server which is willing to perform the
conversion and requires the document transfer over to that server.
There is a security issue in operating on documents not intended for
widespread distribution, which could be partially although not
completely ameliorated by using a secure web connection.

Do you acknowledge and allow the transmission of the document?
(Type 'yes' to acknowledge. You can define non-empty environment
 variable DJVU_ONLINE_ACK to avoid seeing this dialog, or use -a
 command line parameter to any2djvu).
