-=> Quoting Bob Lawrence to John Tserkezis <=-

Hello Bob,

 BL> My complaint is that the unix-wankers make this necessary. There is
 BL> no guarantee that the files will use the same compressor, so they have
 BL> ot be done one at a time instead of as a batch with just one archive
 BL> and one archiver. Dickheads!
 
 JT> In the dos world I imagine you would do the same thing.

 BL> My problem is not *how* to do it, but why? Any fool can work out how
 BL> to do it. It takes genius to do it simply.

 As per the last message, if there is some code available on the de-compression
method(s), modify it, and use that as part of the detection technique.

 You run the decompressor over the file every time.  If it detects cunbatch,
use compress method, if gunbatch, gnucompress, if zunbatch or whatever, use
zip, and if nothing else, assume it's already decompressed and leave it.
 The end result is always the same, you run the decompressor, and it leaves you
with the decompressed file every time.
