Lunzip 1.5-rc1 is ready for testing here

The sha1sum is:
59e602d067225f20fcf386883de3f71357753e90  lunzip-1.5-rc1.tar.lz

Please, test it and report any bugs you find.

Lunzip is a decompressor for lzip files. It is written in C and its small size makes it well suited for embedded devices or software installers that need to decompress files but do not need compression capabilities. Lunzip is fully compatible with lzip-1.4 or newer.

The homepage is at http://www.nongnu.org/lzip/lunzip.html

Changes in this version:

* The new option "-u, --buffer-size", which activates a "low memory" decompression mode, has been added.

If the size of the output buffer is specified with the "--buffer-size" option, lunzip uses the decompressed file as dictionary for distances beyond the buffer size and is able to decompress any file using as little memory as 50 kB, irrespective of the dictionary size used to compress the file. Of course, the smaller the output buffer size used in relation to the dictionary size, the more accesses to disk are needed and the slower the decompression is. This "low memory" mode only works when decompressing to a regular file.

  * File date, permissions, and ownership are now copied like "cp -p" does.

* This version is portable to very old hardware. It has been compiled and tested on a laptop with a 486 processor and 4MiB of RAM.
