I just discovered another need ... however I think this won't easily
implemented.

Currently the complete PDF needs to be parsed into memory, even all I
want from a PDF is the metadata information.

Would it be possible to implement a smart way to extract metadata
information without parsing everything into memory ... ?

Some PDF files I tested needed more then 128M of memory to be parsed
even all I need is Title and Author ... and besides memory it also takes
quite some time, too.

thanks,
