-Tcl UNIX README
----------------
-
-This is the directory where you configure, compile, test, and install UNIX
-versions of Tcl. This directory also contains source files for Tcl that are
-specific to UNIX. Some of the files in this directory are used on the PC or
-MacOSX platform too, but they all depend on UNIX (POSIX/ANSI C) interfaces and
-some of them only make sense under UNIX.
-
-Updated forms of the information found in this file is available at:
-	http://www.tcl.tk/doc/howto/compile.html#unix
-
-For information on platforms where Tcl is known to compile, along with any
-porting notes for getting it to work on those platforms, see:
-	http://www.tcl.tk/software/tcltk/platforms.html
-
-The rest of this file contains instructions on how to do this. The release
-should compile and run either "out of the box" or with trivial changes on any
-UNIX-like system that approximates POSIX, BSD, or System V. We know that it
-runs on workstations from Sun, H-P, DEC, IBM, and SGI, as well as PCs running
-Linux, BSDI, and SCO UNIX. To compile for a PC running Windows, see the README
-file in the directory ../win. To compile for MacOSX, see the README file in
-the directory ../macosx.
-
-How To Compile And Install Tcl:
--------------------------------
-
-(a) If you have already compiled Tcl 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.
-
-(b) If you need to reconfigure because you changed any of the .in or .m4
-    files, you will need to run autoconf to create a new ./configure script.
-    Most users will NOT need to do this since a configure script is already
-    provided.
-
-    (in the tcl/unix directory)
-    autoconf
-
-(c) Type "./configure". This runs a configuration script created by GNU
-    autoconf, which configures Tcl for your system and creates a Makefile. The
-    configure script allows you to customize the Tcl configuration for your
-    site; for details on how you can do this, type "./configure --help" or
-    refer to the autoconf documentation (not included here). Tcl's "configure"
-    supports the following special switches in addition to the standard ones:
-
-	--enable-threads	If this switch is set, Tcl will compile itself
-				with multithreading support.
-	--disable-load		If this switch is specified then Tcl will
-				configure itself not to allow dynamic loading,
-				even if your system appears to support it.
-				Normally you can leave this switch out and Tcl
-				will build itself for dynamic loading if your
-				system supports it.
-	--disable-dll-unloading	Disables support for the [unload] command even
-				on platforms that can support it. Meaningless
-				when Tcl is compiled with --disable-load.
-	--enable-shared		If this switch is specified, Tcl will compile
-				itself as a shared library if it can figure
-				out how to do that on this platform. This is
-				the default on platforms where we know how to
-				build shared libraries.
-	--disable-shared	If this switch is specified, Tcl will compile
-				itself as a static library.
-	--enable-symbols	Build with debugging symbols. By default
-				standard debugging symbols are used. You can
-				specify the value "mem" to include
-				TCL_MEM_DEBUG memory debugging, "compile" to
-				include TCL_COMPILE_DEBUG debugging, or "all"
-				to enable all internal debugging.
-	--disable-symbols	Build without debugging symbols
-	--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
-	--enable-langinfo	Allows use of modern nl_langinfo check for
-				better localization support. This is on by
-				default on platforms where nl_langinfo is
-				found.
-	--disable-langinfo	Specifically disables use of nl_langinfo.
-	--enable-man-symlinks	Use symlinks for linking the manpages that
-				should be reachable under several names.
-	--enable-man-suffix[=STRING]
-				Append STRING to the names of installed manual
-				pages (prior to applying compression, if that
-				is also enabled). If STRING is omitted,
-				defaults to 'tcl'.
-	--enable-man-compression=PROG
-				Compress the manpages using PROG.
-	--enable-dtrace		Enable tcl DTrace provider (if DTrace is
-				available on the platform), c.f. tclDTrace.d
-				for descriptions of the probes made available,
-				see http://wiki.tcl.tk/DTrace for more details
-	--with-encoding=ENCODING Specifies the encoding for compile-time
-				configuration values. Defaults to iso8859-1,
-				which is also sufficient for ASCII.
-	--with-tzdata=FLAG	Specifies whether to install timezone data. By
-				default, the configure script tries to detect
-				whether a usable timezone database is present
-				on the system already.
-
-    Mac OS X only (i.e. completely unsupported on other platforms):
-
-	--enable-framework	Package Tcl as a framework.
-	--disable-corefoundation Disable use of CoreFoundation API and revert
-				to standard select based notifier, required
-				when using naked fork (i.e. not followed by
-				execve).
-
-    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 edit the Makefile to use gcc
-    after configure is run. Also note that you should use the same compiler
-    when building extensions.
-
-    Note: be sure to use only absolute path names (those starting with "/") in
-    the --prefix and --exec-prefix options.
-
-(d) Type "make". This will create a library archive called "libtcl<version>.a"
-    or "libtcl<version>.so" and an interpreter application called "tclsh" that
-    allows you to type Tcl commands interactively or execute script files. It
-    will also create a stub library archive "libtclstub<version>.a" that
-    developers may link against other C code to produce loadable extensions
-    for Tcl.
-
-(e) 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.
-
-(f) Type "make install" to install Tcl 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 standard --prefix and --exec-prefix
-    options to "configure". See the Makefile for information on what
-    directories were chosen; you can override these choices by modifying the
-    "prefix" and "exec_prefix" variables in the Makefile. The installed
-    binaries have embedded within them path values relative to the install
-    directory. If you change your mind about where Tcl should be installed,
-    start this procedure over again from step (a) so that the path embedded in
-    the binaries agrees with the install location.
-
-(g) At this point you can play with Tcl by running the installed "tclsh"
-    executable, or via the "make shell" target, and typing Tcl commands at the
-    interactive prompt.
-
-If you have trouble compiling Tcl, see the URL noted above about working
-platforms. It contains information that people have provided about changes
-they had to make to compile Tcl in various environments. We're also interested
-in hearing how to change the configuration setup so that Tcl compiles on
-additional platforms "out of the box".
-
-Test suite
-----------
-
-There is a relatively complete test suite for all of the Tcl core in the
-subdirectory "tests". To use it 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. See the README
-file in the "tests" directory for more information on the test suite. Note:
-don't run the tests as superuser: this will cause several of them to fail. If
-a test is failing consistently, please send us a bug report with as much
-detail as you can manage to our tracker:

-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

-			  [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.

-    #	1. Use "connect" and "accept" to check for -lsocket, and

-    #	2. Use each function name only once:  can't redo a check because

-    #	3. Use -lnsl and -lsocket only if they supply procedures that
-    #	   aren't already present in the normal libraries.  This is because
-    #	   IRIX 5.2 has libraries, but they aren't needed and they're
-    #	   bogus:  they goof up name resolution if used.
-    #	4. On some SVR4 systems, can't use -lsocket without -lnsl too.
-    #	   To get around this problem, check for both libraries together

-#                       Command to execute to install a stub library.
-#       STLIB_LD -      Base command to use for combining object files
-#                       into a static library.
-#       SHLIB_CFLAGS -  Flags to pass to cc when compiling the components
-#                       of a shared library (may request position-independent
-#                       code, among other things).
-#       SHLIB_LD -      Base command to use for combining object files
-#                       into a shared library.
-#       SHLIB_LD_LIBS - Dependent libraries for the linker to scan when
-#                       creating shared libraries.  This symbol typically
-#                       goes at the end of the "ld" commands that build
-#                       shared libraries. The value of the symbol defaults to
-#                       "${LIBS}" if all of the dependent libraries should
-#                       be specified when creating a shared library.  If
-#                       dependent libraries should not be specified (as on
-#                       SunOS 4.x, where they cause the link to fail, or in
-#                       general if Tcl and Tk aren't themselves shared
-#                       libraries), then this symbol has an empty string
-#                       as its value.
-#       SHLIB_SUFFIX -  Suffix to use for the names of dynamically loadable
-#                       extensions.  An empty string means we don't know how
-#                       to use shared libraries on this platform.
-# TCL_SHLIB_LD_EXTRAS - Additional element which are added to SHLIB_LD_LIBS
-#  TK_SHLIB_LD_EXTRAS   for the build of Tcl and Tk, but not recorded in the
-#                       tclConfig.sh, since they are only used for the build
-#                       of Tcl and Tk.
-#                       Examples: MacOS X records the library version and
-#                       compatibility version in the shared library.  But
-#                       of course the Tcl version of this is only used for Tcl.
-#       LIB_SUFFIX -    Specifies everything that comes after the "libfoo"
-#                       in a static or shared library name, using the $VERSION variable
-#                       to put the version in the right place.  This is used
-#                       by platforms that need non-standard library names.
-#                       Examples:  ${VERSION}.so.1.1 on NetBSD, since it needs
-#                       to have a version after the .so, and ${VERSION}.a
-#                       on AIX, since a shared library needs to have
-#                       a .a extension whereas shared objects for loadable
-#                       extensions have a .so extension.  Defaults to
-#                       ${VERSION}${SHLIB_SUFFIX}.
-#       TCL_LIBS -
-#                       Libs to use when linking Tcl shell or some other
-#                       shell that includes Tcl libs.
-#	CFLAGS_DEBUG -
-#			Flags used when running the compiler in debug mode

-%description
-The Tcl (Tool Command Language) provides a powerful platform for
-creating integration applications that tie together diverse
-applications, protocols, devices, and frameworks.  When paired with
-the Tk toolkit, Tcl provides the fastest and most powerful way to
-create GUI applications that run on PCs, Unix, and Mac OS X.  Tcl
-can also be used for a variety of web-related tasks and for creating
-powerful command languages for applications.

-# create shell variables for most of the configuration options discovered by
