-#	@(#)README	8.6 (Berkeley) 6/20/94
-
-This is the area for building the libdb library.  There are a number
-of porting directories, for various architecture/OS combinations.  Pick
-the one that's closest to yours and try "make".  For the rest of this
-file, I'll use "MACH" as a fake architecture/OS name.
-
-To PORT to a new system, create the following subdirectories and
-symbolic links.
-
-	mkdir MACH		(for example: mkdir sunos.4.0)
-	cd MACH
-	cp ../Makefile .
-	chmod 664 Makefile
-	ln -s ../clib .
-	mkdir include
-	ln -s include sys
-	cd include
-	ln -s ../../include/*.h .
-	rm compat.h
-	cp ../../include/compat.h .
-	chmod 664 compat.h
-	cd ..
-
-The basic idea is that you now have a local area that you can modify.
-In particular, you have local copies of the Makefile and the include
-file compat.h.  Read through the Makefile and compat.h and make whatever
-changes are appropriate to your system.  If there's an architecture
-that's close to yours, you probably should diff the Makefile and
-compat.h in that tree against the standard ones and see what changes
-were necessary, as they're probably necessary for you as well.  Then,
-enter "make" and see what happens!
-
-There are several subroutines that are found in POSIX 1003.2, ANSI
-C, or 4.4BSD that you may not have.  Once you get libdb.a to compile,
-go through the list of undefined routines and add entries to the MISC
-line in the Makefile as necessary.
-
-If you have to add some functions that are missing (and which aren't
-in the PORT/clib directory), please don't add them in the PORT/clib
-directory.  Add them in a MACH/local directory, and add lines of the
-form:
-
-	function.o: local/function.o
-		${CL} -Ilocal local/function.o
-
-to your local Makefile.
-
-Hopefully, over time, we'll develop a set of system directories that
-are known to work.  If you send me the changes that were necessary to
-make your system work, this will happen much more quickly.
-
-In some of the system directories, you'll see a file named OTHER_PATCHES.
-This is a set of patches which you'll have to make from the top-level db
-directory to get libdb.a to run on this system:
-
-	cd ..
-	patch < PORT/MACH/OTHER_PATCHES
-
-If patch prompts you for the name of the file to modify (some versions
-of patch don't figure it out on their own) use the file name which patch
-displays.
-
-Some knobs you may have to turn:
-
-In include/db.h:
-	Before attempting to build libdb, you should look through the
-	db.h file, and adjust it as necessary for your system.  The
-	only adjustments that you should need to make are for the
-	fixed sized typedef's at the top of the file.  Make sure they're
-	right for your system.
-
-In include/compat.h:
-	Before attempting to build libdb, you should look through the
-	compat.h file, and adjust it as necessary for your system.
-	It's possible to use the #ifndef construct to figure out if a
-	#ifdef has been set, but C provides no similar method to figure
-	out if a typedef has been done.  Your compile errors should
-	give you a good indication of which ones you need.
-
-You may see warning messages about illegal pointer combinations.  You may
-also see lots of warning messages about #define's being redefined.  These
-can mostly be ignored.  I usually ignore warning messages until something
-doesn't work.  Some systems produce thousands of lines of useless warnings,
-bless their little hearts.
-
-The other parts of the PORT directory are as follows:
-
-	The directory PORT/clib is a set of functions that the 4.4BSD
-	C library had and which your system may not have.  They are
-	added to the MISC line of the Makefile if they aren't defined
-	when you try and load libdb.a.
-	
-	The directory PORT/include is header files that the 4.4BSD
-	system had which your system may not have.  There is also
-	one really important extra one, named compat.h, which is a
-	set of compatibility work-arounds that you'll almost certainly
-	have to copy and modify for a new system.
-
-	The symbolic link PORT/sys points to the PORT/include directory
-	so that includes of the form <sys/include.h> work.
-
-Some of the more common portability problems:
-
-	If you don't have:
-
-		memmove(3):	add memmove.o
-		mkstemp(3):	add mktemp.o
-
-			... to the MISC line in the Makefile.
-
-	If you don't have snprintf/vsnprintf(3), add snprintf.o to the
-	MISC line in the Makefile.  This workaround depends on your
-	system having vsprintf(3) -- if you don't, there's no workaround
-	other than changing the source code to not use the snprintf calls.
-	If you have to make that change, check to see if your vsprintf
-	returns a length or a char *; if it's the latter, make sure you
-	set VSPRINTF_CHARSTAR in the MACH/include/compat.h file.
-
-Installing the DB library:
-
-	The Makefile builds a C library named libdb.a.  This file needs
-	to be installed in a place where the loader will automatically
-	look for it (or, if you're building it for a single project,
-	wherever that project's Makefile loads it from).
-
-	In addition, the header file PORT/include/db.h must be copied to
-	a directory (often /usr/include/) where programs that use the
-	db package can include it in their source.  (If you intend to use
-	the ndbm interface to libdb, you'll need to copy the header file
-	PORT/include/ndbm.h as well.)
