Numbers may be followed by a multiplier: k = kB = 10^3 = 1000,
Ki = KiB = 2^10 = 1024, M = 10^6, Mi = 2^20, G = 10^9, Gi = 2^30, etc...
+The bidimensional parameter space of LZMA can't be mapped to a linear
+scale optimal for all files. If your files are large, very repetitive,
+etc, you may need to use the \fB\-\-match\-length\fR and \fB\-\-dictionary\-size\fR
+options directly to achieve optimal performance.
