+This directory contains various files derived from CDDL sources that
+are used by the ZFS bootstrap:
+
+ fletcher.c checksum support
+ sha256.c checksum support
+ lzjb.c compression support
+ zfssubr.c mostly checksum and compression support
+ zfsimpl.h mostly describing the physical layout
+
+The files fletcher.c, lzjb.c and sha256.c are largely identical to the
+ZFS base code (with write support removed) and could be shared but
+that might complicate future imports from OpenSolaris.
