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. .SH OPTIONS .TP \fB\-h\fR, \fB\-\-help\fR @@ -36,6 +48,9 @@ suppress all messages \fB\-t\fR, \fB\-\-test\fR test compressed file integrity .TP +\fB\-u\fR, \fB\-\-buffer\-size=\fR<bytes> +set output buffer size in bytes +.TP \fB\-v\fR, \fB\-\-verbose\fR be verbose (a 2nd \fB\-v\fR gives more) .PP |
