installers that need to decompress files but do not need compression
capabilities.
+Lunzip uses the same well-defined exit status values used by bzip2,
+which makes it safer when used in pipes or scripts than compressors
+returning ambiguous warning values, like gzip.
+
+The 4 factor integrity checking of the lzip format guarantees that the
+decompressed version of the data is identical to the original. This
+guards against corruption of the compressed data, and against undetected
+bugs in lunzip (hopefully very unlikely). The chances of data corruption
+going undetected are microscopic. Be aware, though, that the check
+occurs upon decompression, so it can only tell you that something is
+wrong. It can't help you recover the original uncompressed data.

If you ever need to recover data from a damaged lzip file, try the
lziprecover program.
