Yeah, those two are the most straightforward. It really gets ugly when you
try to write the zip files. I was forced to use some 1.2 features (like
the java.uti.jar package and the ZipEntry.getCompressedSize() method)
because there was not other way to implement it. I still do not get how
one is supposed to write a input stream and set the CRC of an uncompressed
ZipEntry without reading the stream twice. If you have figured that one
out please tell me how you did it. I threw in a quick hack to set the crc
to 0 and that seemed to work but it is not the "right" solution. I think
I will end up needing to implement the java.util.jar package in Kaffe for
this all to work. There is really no reason to implement a custom manifest
parser and writer whan 1.2 makes these classes standard.
