+This feature improves the performance and compression ratio of
+highly-compressible blocks. Blocks whose contents can compress to 112 bytes
+or smaller can take advantage of this feature.
+
+When this feature is enabled, the contents of highly-compressible blocks are
+stored in the block "pointer" itself (a misnomer in this case, as it contains
+the compresseed data, rather than a pointer to its location on disk). Thus
+the space of the block (one sector, typically 512 bytes or 4KB) is saved,
+and no additional i/o is needed to read and write the data block.
+
+This feature becomes \fBactive\fR as soon as it is enabled and will
+never return to being \fBenabled\fR.
