 How To Compile And Install Tk:
 ------------------------------
 
 (a) Make sure that the Tcl release is present in the directory
-    ../../tcl<version> (or else use the "--with-tcl" switch described
-    below).  This release of Tk will only work with the equivalently
-    versioned Tcl release. Also, be sure that you have configured Tcl before
-    you configure Tk.

+    This release of Tk will only work with the equivalently versioned Tcl
+    release. Also, be sure that you have configured Tcl before you configure
+    Tk.
 
 (b) Check for patches as described in ../README.
 
 (c) If you have already compiled Tk once in this directory and are now
     preparing to compile again in the same directory but for a different
-    platform, or if you have applied patches, type "make distclean" to
-    discard all the configuration information computed previously.
-
-(d) Type "./configure".  This runs a configuration script created by GNU
-    autoconf, which configures Tk for your system and creates a Makefile.
-    The configure script allows you to customize the Tk configuration for
-    your site; for details on how you can do this, type "./configure
-    -help" or refer to the autoconf documentation (not included here).
-    Tk's "configure" script supports the following special switches in
-    addition to the standard ones:
+    platform, or if you have applied patches, type "make distclean" to discard
+    all the configuration information computed previously.

+    configure script allows you to customize the Tk configuration for your
+    site; for details on how you can do this, type "./configure -help" or
+    refer to the autoconf documentation (not included here). Tk's "configure"
+    script supports the following special switches in addition to the standard
+    ones:
+
 	--with-tcl=DIR		Specifies the directory containing the Tcl
 				binaries and Tcl's platform-dependent
-				configuration information.  By default
-				the Tcl directory is assumed to be in the
-				location given by (a) above.
-	--enable-threads	If this switch is set, Tk will compile

+	--with-x=DIR		Tells configure where to find an installation
+				of the X Window System. Not normally needed.
+	--enable-threads	If this switch is set, Tk will compile itself
+				with multithreading support.
 	--enable-shared		If this switch is specified, Tk will compile
 				itself as a shared library if it can figure

 	--disable-shared	If this switch is specified, Tk will compile
 				itself as a static library.

+	--enable-symbols	Build with debugging symbols. By default
+				standard debugging symbols are used. You can

 				TCL_MEM_DEBUG memory debugging.
 	--disable-symbols	Build without debugging symbols
-	--disable-xft		Disable support for antialiased fonts via
-				the Freetype/xft library. By default,

 	--enable-64bit		Enable 64bit support (where applicable)
 	--disable-64bit		Disable 64bit support (where applicable)
 	--enable-64bit-vis	Enable 64bit Sparc VIS support
 	--disable-64bit-vis	Disable 64bit Sparc VIS support

+				Freetype/xft library. By default, this is
+				switched on whenever the configure script can
+				detect the required libraries.
 	--enable-man-symlinks	Use symlinks for linking the manpages that
 				should be reachable under several names.
 	--enable-man-compression=PROG
 				Compress the manpages using PROG.
 	--enable-man-suffix=STRING

     Mac OS X only:

 	--enable-framework	Package Tk as a framework.
 	--disable-corefoundation Disable use of CoreFoundation API.
 	--enable-aqua		Use Aqua windowingsystem rather than X11,
-				requires --enable-corefoundation with Tcl

-    Note: by default gcc will be used if it can be located on the PATH.
-    if you want to use cc instead of gcc, set the CC environment variable
-    to "cc" before running configure. It is not safe to change the Makefile
-    to use gcc after configure is run.
-
-    Note: be sure to use only absolute path names (those starting with "/")
-    in the --prefix and --exec-prefix options.
-
-(e) Type "make".  This will create a library archive called
-    "libtk<version>.a" or "libtk<version>.so" and an interpreter
-    application called "wish" that allows you to type Tcl/Tk commands
-    interactively or execute script files.  It will also create a
-    stub library archive "libtkstub<version>.a" that developers may
-    link against other C code to produce loadable extensions that call
-    into Tk's public interface routines.
-
-(f) If the make fails then you'll have to personalize the Makefile
-    for your site or possibly modify the distribution in other ways.
-    First check the porting Web page above to see if there are hints
-    for compiling on your system.  If you need to modify Makefile,
-    there are comments at the beginning of it that describe the things
-    you might want to change and how to change them.
-
-(g) Type "make install" to install Tk's binaries and script files in
-    standard places.  You'll need write permission on the installation
-    directories to do this.  The installation directories are
-    determined by the "configure" script and may be specified with
-    the --prefix and --exec-prefix options to "configure".  See the
-    Makefile for information on what directories were chosen.  You
-    should not override these choices by modifying the Makefile, or by
-    copying files post-install.  The installed binaries have embedded within
-    them path values relative to the install directory.  If you change your
-    mind about where Tk should be installed, start this procedure over again        from step (a) so that the path embedded in the binaries agrees with the
-    install location.

 If you have trouble compiling Tk, see the URL noted above about working

 Test suite
 ----------
 
-Tk has a substantial self-test suite, consisting of a set of scripts in
-the subdirectory "tests".  To run the test suite just type "make test"
-in this directory.  You should then see a printout of the test files
-processed.  If any errors occur, you'll see a much more substantial
-printout for each error.  In order to avoid false error reports, be sure
-to run the tests with an empty resource database (e.g., remove your
-.Xdefaults file or delete any entries starting with *).  Also, don't
-try to do anything else with your display or keyboard while the tests
-are running, or you may get false violations.  See the README file in
-the "tests" directory for more information on the test suite.
-
-If the test suite generates errors, most likely they are due to non-
-portable tests that are interacting badly with your system configuration.
-We are gradually eliminating the non-portable tests, but this release
-includes many new tests so there will probably be some portability
-problems.  As long as the test suite doesn't core dump, it's probably
-safe to conclude that any errors represent portability problems in the
-test suite and not fundamental flaws with Tk.

 There are also a number of visual tests for things such as screen layout,
-Postscript generation, etc.  These tests all have to be run by manually
-enabling the "userInteraction" constraint when testing, and the results
-have to be verified visually..  This can be done with
-     make test TESTFLAGS="-constraints userInteraction"
-Some tests will present a main window with a bunch of menus, which you can
-use to select various tests.
