Ok. I'll do it.
I will put the [filenames] section at the end of file. That way appending
to the file is dead simple.
The header structure will be the same, so between 10-20 bytes are
always the [filenames] position.
I was thinking more about the metadata stuff. If we agree on a filename,
like .metadata-kiss, and attache it as a simple file, there is no importance
where in the archive should be placed (but I think should be placed at
[3. file = metadata file]
But metadata is really for future consideration (if people find this
archive format useful).
I will also make some test archive file along with the kiss and unkiss
program, to easy implementing.
Here is the updated specification (I added two more faq entries,
max filesize and max filename length):
