Does make it a bit difficult - especially the lack of useful information.
Hopefully eventually we can support either but I don't intend rewriting the
dlls, we are working at making a vcl only version but will take a while,
then I want to add support for Deflate64 before attacking encryption but
will need to make the encryption layer fairly general even if we end up with
only 3 schemes (the trouble is that once the format splits it is likely to
shatter).
