+# @(#)README 8.27 (Berkeley) 9/1/94
+
+This is version 1.85 of the Berkeley DB code.
+
+For information on compiling and installing this software, see the file
+PORT/README.
+
+Newer versions of this software will periodically be made available by
+anonymous ftp from ftp.cs.berkeley.edu. An archive in compressed format
+is in ucb/4bsd/db.tar.Z, or in gzip format in ucb/4bsd/db.tar.gz. If
+you'd like to receive announcements of future releases of this software,
+send email to the contact address below.
+
+Email questions may be addressed to Keith Bostic at bostic@cs.berkeley.edu.
+
+============================================
+Distribution contents:
+
+Makefile.inc Ignore this, it's the 4.4BSD subsystem Makefile.
+PORT The per OS/architecture directories to use to build
+ libdb.a, if you're not running 4.4BSD. See the file
+ PORT/README for more information.
+README This file.
+btree The B+tree routines.
+changelog List of changes, per version.
+db The dbopen(3) interface routine.
+docs Various USENIX papers, and the formatted manual pages.
+hash The extended linear hashing routines.
+man The unformatted manual pages.
+mpool The memory pool routines.
+recno The fixed/variable length record routines.
+test Test package.
+
+============================================
+Debugging:
+
+If you're running a memory checker (e.g. Purify) on DB, make sure that
+you recompile it with "-DPURIFY" in the CFLAGS, first. By default,
+allocated pages are not initialized by the DB code, and they will show
+up as reads of uninitialized memory in the buffer write routines.
