Funnily enough, lziprecover is the most capable decompressor for the lzip format. It is currently the only one featuring random access to the data in multimember files:


-D range
Decompress only a range of bytes starting at decompressed byte position 'begin' and up to byte position 'end - 1'. This option provides random access to the data in multimember files; it only decompresses the members containing the desired data. In order to guarantee the correctness of the data produced, all members containing any part of the desired data are decompressed and their integrity is verified.

Well, that's fine for me, I can simply use "lziprecover --list" when I
need the information. No need to double that code to lzip, if it makes
portability problems.

Good, thanks. For the next version I'll either implement --list in lzip or document to use lziprecover instead.

Best regards,
