 .SH DESCRIPTION
-Lunzip \- Decompressor for lzip files.
+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.
+.PP
+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.
