+QUICK AND DIRTY
+===============
+
+Execute the following from the src/ directory:
+
+    ./configure    # try to figure out all implementation differences
+
+    cd lib         # build the basic library that all programs need
+    make           # use "gmake" everywhere on BSD/OS systems
+
+    cd ../libfree  # continue building the basic library
+    make
+
+    cd ../libroute # only if your system supports 4.4BSD style routing sockets
+    make           # only if your system supports 4.4BSD style routing sockets
+
+    cd ../libxti   # only if your system supports XTI
+    make           # only if your system supports XTI
+
+    cd ../intro    # build and test a basic client program
+    make daytimetcpcli
+    ./daytimetcpcli 127.0.0.1
+
+If all that works, you're all set to start compiling individual programs.
+
+Notice that all the source code assumes tabs every 4 columns, not 8.
+
+MORE DETAILS
+============
+
+5.  If you need to make any changes to the "unp.h" header, notice that it
+    is a hard link in each directory, so you only need to change it once.
+
+6.  Go into the "lib/" directory and type "make".  This builds the library
+    "libunp.a" that is required by almost all of the programs.  There may
+    be compiler warnings (see NOTES below).  This step is where you'll find
+    all of your system's dependencies, and you must just update your cf/
+    files from step 1, rerun "config" and do this step again.
+
+6.  Go into the "libfree/" directory and type "make".  This adds to the
+    "libunp.a" library.  The files in this directory do not #include
+    the "unp.h" header, as people may want to use these functions
+    independent of the book's examples.
+
+8.  Once the library is made from steps 5 and 6, you can then go into any
+    of the source code directories and make whatever program you are
+    interested in.  Note that the horizontal rules at the beginning and
+    end of each program listing in the book contain the directory name and
+    filename.
+
+    BEWARE: Not all programs in each directory will compile on all systems
+    (e.g., the file src/advio/recvfromflags.c will not compile unless your
+    system supports the IP_RECVDSTADDR socket option).  Also, not all files
+    in each directory are included in the book.  Beware of any files with
+    "test" in the filename: they are probably a quick test program that I
+    wrote to check something, and may or may not work.
+
+NOTES
+-----
+
+- Many systems do not have correct function prototypes for the socket
+  functions, and this can cause many warnings during compilation.
+  For example, Solaris 2.5 omits the "const" from the 2nd argument
+  to connect().  Lots of systems use "int" for the length of socket
+  address structures, while Posix.1g specifies "size_t".  Lots of
+  systems still have the pointer argument to [sg]etsockopt() as a
+  "char *" instead of a "void *", and this also causes warnings.
+
+- SunOS 4.1.x: If you are using Sun's acc compiler, you need to run
+  the configure program as
+
+        CC=acc CFLAGS=-w CPPFLAGS=-w ./configure
+
+  Failure to do this results in numerous system headers (<sys/sockio.h>)
+  not being found during configuration, causing compile errors later.
+
+- If your system supports IPv6 and you want to run the examples in the
+  book using hostnames, you must install the latest BIND release.  You
+  can get it from ftp://ftp.vix.com/pub/bind/release.  All you need from
+  this release is a resolver library that you should then add to the
+  LDLIBS and LDLIBS_THREADS lines.
+
+- IPv6 support is still in its infancy.  There may be differences
+  between the IPv6 sockets API specifications and what the vendor
+  provides.  This may require hand tweaking, but should get better
+  over time.
+
+- If your system supports an older draft of the Posix pthreads standard,
+  but configure detects the support of pthreads, you will have to disable
+  this by hand.  Digital Unix V3.2C has this problem, for example, as it
+  supports draft 4, not the final draft.
+
+  To fix this, remove wrappthread.o from LIB_OBJS in "Make.defines" and
+  don't try to build and run any of the threads programs.
+
+COMMON DIFFERENCES
+------------------
+
+These are the common differences that I see in various headers that are
+not "yet" at the level of Posix.1g or X/Open XNS Issue 5.
+
+- getsockopt() and setsockopt(): 5th argument is not correct type.
+
+- t_bind(): second argument is missing "const".
+
+- t_connect(): second argument is missing "const".
+
+- t_open(): first argument is missing "const".
+
+- t_optmsmg(): second argument is missing "const".
+
+- If your <xti.h> defines the members of the t_opthdr{} as longs,
+  instead of t_uscalar_t, some of the printf formats of these value
+  might generate warnings from your compiler, since you are printing
+  a long without a corresponding long format specifier.
