+	  A compression utility that excels at compressing large files
+	  (usually > 10-50 MB). Larger files and/or more free RAM means
+	  that the utility will be able to more effectively compress
+	  your files (ie: faster / smaller size), especially if the
+	  filesize(s) exceed 100 MB. You can either choose to optimise
+	  for speed (fast compression / decompression) or size,
+	  but not both.
