+
+2004-03-17  Dan Razzell <research@starfishsystems.ca>

+2004-02-17  Dan Razzell <research@starfishsystems.ca>
+
+	TLS 1.5.0 RELEASE
+
+2004-02-12  Dan Razzell	<research@starfishsystems.ca>
+

+	* tls.htm:	Document callback behaviors.
+
+2004-02-11  Dan Razzell	<research@starfishsystems.ca>
+
+	* tests/tlsIO.test:
+	* remote.tcl:	Complete private key name changes from 2001-06-21.
+
+2004-02-03  Dan Razzell <research@starfishsystems.ca>
+
+	* Makefile.in:	Removed circular dependency.
+	* tlsInt.h:	Make function declarations explicit.

+
+	* pkgIndex.tcl.in:

+	* tests/tlsIO.test: updated version to 1.5.
+
+2003-10-07  Dan Razzell	<research@starfishsystems.ca>
+
+	* tests/ciphers.test: updated list of tested ciphers to correspond
+	* with those available from OpenSSL. [Request #811981]
+
+2003-10-07  Dan Razzell <research@starfishsystems.ca>
+
+	* tls.c: added CONST with intent similar to those from 2002-02-04.
+	[Request #811911]
+
+2003-07-07  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tls.c (Tls_Init):   added tls::misc command provided by
+	* tlsX509.c:          Wojciech Kocjan (wojciech kocjan.org)
+	* tests/keytest1.tcl: to expose more low-level SSL commands
+	* tests/keytest2.tcl:
+
+2003-05-15  Dan Razzell	<research@starfishsystems.ca> 
+
+	* tls.tcl:
+	* tlsInt.h:
+	* tls.c: add support for binding a password callback to the socket.
+	Now each socket can have its own command and password callbacks instead
+	of being forced to have all password management pass through a common
+	procedure.  The common password procedure is retained for compatibility
+	but its use should be DEPRECATED.
+	Add version command to return OpenSSL version string.
+	Remove unstable workarounds needed for verify in obsolete versions of
+	OpenSSL.
+	Fix memory leak. [Request #640660]
+	More casts to eliminate compiler warnings.
+
+	* tls.htm: document password callback.
+	Correct technical and typographic errors.
+
+	* README.txt: identify versions of OpenSSL which fix known problems.
+	General warning of security problems in older versions of OpenSSL.
+
+2002-02-04  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tls.htm:
+	* tls.c: added support for local certificate status check, as well
+	as returning the # of bits in the session key. [Patch #505698] (rose)
+
+	* tls.c:
+	* tlsIO.c:
+	* tlsBIO.c: added CONSTs to satisfy Tcl 8.4 sources.  This may
+	give warnings when compiled against 8.3, but they can be ignored.
+
+	* tests/simpleClient.tcl:
+	* tests/simpleServer.tcl: point to updated client/server key files.
+
+	* tests/tlsIO.test:
+	* tests/ciphers.test: updated to load tls from build dir.
+
+	* Makefile.in: removed strncasecmp from default object set.  This
+	is only needed on the Mac, and Tcl stubs provides it.
+
+	* configure: regen'ed.
+	* configure.in: updated to 1.5.0 for next release.
+	Changed default openssl location to /usr/local/ssl (this is where
+	openssl 0.9.6c installs by default).
+	Changed to use public Tcl headers (private not needed).
+
+2001-06-21  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	TLS 1.4.1 RELEASE
+
+	* configure: added configure to CVS
+	* configure.in: moved to patchlevel 1.4.1
+
+	* Makefile.in: corrected 'dist' target
+
+	* tests/certs/file.srl:
+	* tests/certs/ca.pem:
+	* tests/certs/client.key:
+	* tests/certs/client.pem:
+	* tests/certs/client.req:
+	* tests/certs/privkey.pem:
+	* tests/certs/server.key:
+	* tests/certs/server.pem:
+	* tests/certs/server.req:
+	* tests/certs/cacert.pem: replaced by new ca.pem
+	* tests/certs/skey.pem: replaced by new server.key
+	* tests/certs/ckey.pem: replaced by new client.key
+	* tests/certs/README.txt: new set of test certificates with some
+	README info on their generation.
+
+	* tests/ciphers.test: updated ciphers expected with default
+	openssl build.
+
+	* tests/tclIO.test: updated to use new names for certs/keys.
+
+2001-03-14  Jeff Hobbs  <jeffh@gimlet.activestate.com>
+
+	* tls.c (Tls_Init): add do/while for random number initialization
+	to work around some OSes quirks.  (Ralph.Billes@teltech.com.au)
+
+2000-09-07  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* tlsIO.c (Tls_ChannelType): set typeName field of channel type to
+	"tls" (this got lost in move to dynamic version compatability
+	checking).
+
+2000-08-23  Jeff Hobbs  <hobbs@scriptics.com>
+
+	TLS 1.4 RELEASED
+
+	* Makefile.in (dist): create dist target for archive distributions
+
+	* tests/tlsIO.test (tlsIO-8.1): added a delay on the accept close
+	to make the test work with OpenSSL on Windows (doesn't affect
+	other builds).
+
+	* tls.htm: updated with notes for 1.4.
+
+2000-08-21  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* tests/tlsIO.test: require at least tls1.4 in test suite.
+
+2000-08-18  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* tls.c (Tls_Init): added call to RAND_seed to seed the SSL random
+	number generator.  Without this, OpenSSL 0.9.5 chokes, and in any
+	case it is a big security hole to do without it.
+
+	* configure.in (OPENSSL): added NO_IDEA and NO_RC5 defines by
+	default when compiling with OpenSSL.
+
+	* tlsInt.h: added err.h include
+
+	* tlsBIO.c:
+	* tlsIO.c: corrected pedantic cast errors.
+
+2000-08-16  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* tests/ciphers.test: improved ability to change constraint
+	setting for whether user compiled against RSA or OpenSSL libs.
+
+	* tls.c (Tls_Init): corrected interpretation of version number
+	(patchlevel and release/serial were swapped).
+
+2000-08-15  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* README.txt: added notes about need to use 8.2.0+.
+
+	* tlsInt.h:
+	* tls.c:
+	* tlsIO.c: corrected structure initialization to work when
+	compiling with 8.2.  Now compiles with 8.2+ and tested to work
+	with 8.2+ and dynamically adjust to the version of Tcl it was
+	loaded into.  TLS will fail the test suite with Tcl 8.2-8.3.1.
+
+	* tests/all.tcl: added catch around ::tcltest::normalizePath
+	because it doesn't exist in pre-8.3 tcltest.
+
+	* tests/simpleClient.tcl: 
+	* tests/simpleServer.tcl: added simple client/server test scripts
+	that use test certs and can do simple stress tests.
+
+2000-08-14  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* tlsInt.h:
+	* tlsIO.c:
+	* tlsBIO.c:
+	* tls.c: changed around to only working with 8.2.0+ (8.3.2+
+	preferred), with runtime checks for pre- and post-io-rewrite.
+
+	* tls.c (Tls_Init): changed it to require 8.3.2 when Tcl_InitStubs
+	was called because we don't want people using TLS with the
+	original stacked channel implementation.
+
+2000-07-26  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* merged all changes from tls-1-3-io-rewrite back into main branch
+
+	* tests/tlsIO.test: updated comments, fixed a pcCrash case that
+	was due to debug assertion in Windows SSL.
+
+	* tls.c (ImportObjCmd): removed unnecessary use of 'bio' arg.
+	(Tls_Init): check return value of SSL_library_init.  Also lots of
+	whitespace cleanup (more like Tcl Eng style guide), but not all
+	code was cleaned up.
+
+	* tlsBIO.c: minor whitespace cleanup
+
+	* tlsIO.c: minor whitespace cleanup.
+	(TlsInputProc, TlsOutputProc): Added ERR_clear_error before calls
+	to BIO_read or BIO_write, because we could otherwise end up
+	pulling an error off the stack that didn't belong to us.  Also
+	cleanup up excessive use of gotos.
+
+2000-07-20  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* tests/tlsIO.test: corrected various tests to be correct for TLS
+	stacked channels (as opposed to the standard sockets the test
+	suite was adopted from).  Key differences are that TLS cannot
+	operate in one process without all channels being non-blocking, or
+	the handshake will block, and handshaking must be forced in some
+	cases.  Also, handshakes don't seem to complete unless the client
+	has placed at least one byte for the server to read in the channel.
+
+	* tests/remote.tcl: corrected the finding of tests certificates
+
+	* tlsIO.c (TlsCloseProc): removed deleting of timer handler as
+	that is handled by Tls_Clean.
+
+	* tls.tcl (tls::_accept): corrected the internal _accept to
+	trickle callback errors to the user.
+
+	* Makefile.in: made the install-binaries target regenerate the
+	pkgIndex.tcl correctly.  The test target probably shouldn't screw
+	it up, but this is to be on the safe side.
+
+2000-07-17  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* pkgIndex.tcl.in:
+	* configure.in: updated version to 1.4
+
+2000-07-13  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* tests/tlsIO.test: enabled tests 2.10, 7.[1245] (there is no 3),
+	which now pass.  Added some comments to other failing tests.
+
+2000-07-11  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* tlsIO.c: changed all the channel procs to start with Tls* for
+	better parity when comparing with Transform channel procs.
+	Rewrote TlsWatchProc, added TlsNotifyProc according to the new
+	channel design, which also leaves TlsChannelHandler unused.
+
+	* tlsBIO.c (BioCtrl): changed BIO_CTRL_FLUSH case to use
+	Tcl_WriteRaw instead of Tcl_Flush (to operate on correct channel
+	in the stack instead of starting at the top again).  Would
+	otherwise cause a recursive stack bomb when implicit handshaking
+	took effect.
+
+	* tests/tlsIO.test: removed changes made to test suite (all tests
+	that ran before now pass correctly), and changed some accept proc
+	args to reflect that a sock is an arg, not a file.
+
+2000-07-10  Jeff Hobbs  <hobbs@scriptics.com>
+
+	* tlsBIO.c (BioWrite, BioRead): changed Tcl_Read/Write to
+	Tcl_ReadRaw/TclWriteRaw.
+
+	* tls.c: added use of Tcl_GetTopChannel after Tcl_GetChannel and
+	got return value from Tcl_StackChannel.
+
+	* tests/tlsIO.test: added some handshaking that shouldn't be
+	necessary, but we crash otherwise (needs more testing).
+
+	* tlsIO.c: added support for "corrected" stacked channels.  All
+	the above channels are in TCL_CHANNEL_VERSION_2 #ifdefs.
+
+2000-06-05  Scott Stanton  <stanton@ajubasolutions.com>
+
+	* Makefile.in: Fixed broken test target.
+
+	* tlsInt.h: 
+	* tls.c: Cleaned up declarations of Tls_Clean to avoid errors on
+	Windows (lint).
+
+2000-06-05  Brent Welch <welch@ajubasolutions.com>
+
+	* tls.c, tlsIO.c:  Split Tls_Free into Tls_Clean, which does
+	the SSL cleanup, and the Tcl_Free call.  It is important to shutdown
+	the SSL state "synchronously" during a stacked flush.
+
+2000-06-01  Scott Stanton  <stanton@ajubasolutions.com>
+
+	* tlsIO.c: Restored call to Tcl_NotifyChannel from ChannelHandler
+	to ensure that events propagate from the lower driver.  This may
+	result in an infinite loop in some cases, so this is not a total
+	fix.  This may be sufficient for now, however. [Bug: 5623]
+
+2000-06-01  Scott Stanton  <stanton@scriptics.com>
+
+	* tlsIO.c: Restore the previous version.  Fixed the CloseProc so
+	it unregisters the channel handler on the superceded channel
+	instead of the upper channel. Also removed the call to
+	Tcl_NotifyChannel in the ChannelHandler because this will result
+	in an infinite loop if data is ever buffered in the BIO
+	structure. [Bug: 5623]
+
+2000-05-31  Brent Welch <welch@scriptics.com>
+
+	* tls.c: Change the ChannelHandler to be registered on the main
+	channel as oppsed to the "parent", or superceeded, channel.  This
+	is because the socket driver notifies the main channel, and there
+	are times with the main channel gets closed, but the superceded
+	one is not yet closed.  If the channel handler gets triggered in
+	this half-open state it is associated with the superceeded
+	channedl, but uses its private pointer to the main channel, which
+	is mostly destroyed.  Eliminated the redundant call to
+	Tcl_NotifyChannel from TlsWatchProc. [Bug: 5623]

+
+TLS (aka SSL) Channel - can be layered on any bi-directional Tcl_Channel.
+
+Both client and server-side sockets are possible, and this code should work
+on any platform as it uses a generic mechanism for layering on SSL and Tcl.
+
+Full filevent sematics should also be intact - see tests directory for
+blocking and non-blocking examples.
+
+The current release is TLS 1.6, with binaries built against OpenSSL 0.9.8g.
+For best security and function, always compile from source with the latest
+official release of OpenSSL (http://www.openssl.org/).
+
+TLS requires Tcl 8.2.0+, with 8.3.2+ preferred.  The stacked channel
+implementation in Tcl was originally introduced in 8.2.0 (previously the
+Trf patch) and rewritten for 8.3.2+ due to inherent limitations in the
+earlier implementation.  TLS should compile with any stubs-capable Tcl
+interpreter, but will require 8.2+ when loaded.  There are known
+limitations in the 8.2.0-8.3.1 stacked channel implementation, so it is
+encouraged that people use TLS with an 8.3.2+ Tcl interpreter.  These
+modifications are by Jeff Hobbs.
+
+Non-exclusive credits for TLS are:

+\`configure' configures tls 1.6.7 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [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.
+
+Fine tuning of the installation directories:
+  --bindir=DIR            user executables [EPREFIX/bin]
+  --sbindir=DIR           system admin executables [EPREFIX/sbin]

+  --libdir=DIR            object code libraries [EPREFIX/lib]
+  --includedir=DIR        C header files [PREFIX/include]
+  --oldincludedir=DIR     C header files for non-gcc [/usr/include]

+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+2010-09-09  Jan Nijtmans  <nijtmans@users.sf.net>
+
+	* tcl.m4: [FREQ #3058486] TEA_LOAD_CONFIG doesn't set all BUILD_ vars
+	Slightly related: defining BUILD_$1 on all platforms - not only win -
+	allows the -fvisibility feature to be used in extensions as well, at

+
+2010-08-19  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4: add TEA_ADD_CLEANFILES macro to make adding cleanfiles
+	easier, and add *.exp to CLEANFILES Windows default.
+	(TEA_MAKE_LIB): Enhanced to check for MSVC that requires manifests
+	and auto-embed it into proj DLL via MAKE_SHARED_LIB.  Also define
+	VC_MANIFEST_EMBED_DLL and VC_MANIFEST_EMBED_EXE that do the same
+	magic in case it is needed for extended TEA projects.

+
+	* tcl.m4: add /usr/lib64 to set of auto-search dirs. [Bug 1230554]
+	Auto-define BUILD_$PACKAGE_NAME so users don't need to.  This
+	needs to correspond with $pkg.h define magic for TCL_STORAGE_CLASS.
+	Auto-define CLEANFILES.  Users can expand it.
+	(SHLIB_LD_LIBS): define to '${LIBS}' default and change it only if

+	very funky linkers.
+	(TEA_LOAD_CONFIG): When loading config for another extension,
+	auto-add stub libraries found with TEA_ADD_LIBS.  Eases
+	configure.in for modules like itk and img::*.
+	(TEA_EXPORT_CONFIG): Add standardized function for exporting a

+
+2005-11-27  Daniel Steffen  <das@users.sourceforge.net>
+
+	* tcl.m4 (Darwin): add 64bit support, add CFLAGS to SHLIB_LD to

+	missing quoting.
+	(TEA_PROG_TCLSH, TEA_PROG_WISH): fix incorrect assumption that
+	install location of tclConfig.sh/tkConfig.sh allows to determine
+	the tclsh/wish install dir via ../bin. Indeed tcl/tk can be
+	configured with arbitrary --libdir and --bindir (independent of
+	prefix) and such a configuration is in fact standard with Darwin
+	framework builds. At least now also check ${TCL_PREFIX}/bin
+	resp. ${TK_PREFIX}/bin for presence of tclsh resp. wish (if tcl/tk
+	have been configured with arbitrary --bindir, this will still not

+	AC_SUBST($1_BIN_DIR) to TEA_LOAD_CONFIG so that packages that load
+	the configuration of another package can know where they loaded
+	it from.
+
+2005-03-18  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4 (TEA_CONFIG_CFLAGS): correct 2005-03-17 change to have
+	variant LD_SEARCH_FLAGS for gcc and cc builds.
+
+	* tcl.m4 (TEA_PROG_TCLSH, TEA_PROG_WISH): correct x-compile check.
+
+2005-03-17  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4: Correct gcc build and HP-UX-11.
+
+2005-02-08  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4 (TEA_ADD_LIBS): don't touch lib args starting with -.
+	(TEA_CONFIG_CFLAGS): only define _DLL for CE in shared build.
+	(TEA_MAKE_LIB): set RANLIB* to : on Windows (it's not needed).
+
+2005-02-01  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4: redo of 2005-01-27 changes to correctly handle paths
+	with spaces.  Win/CE and Win/64 builds now require a prebuilt
+	tclsh to handle conversion to short pathnames.  This is done in
+	the new TEA_PATH_NOSPACE macro.  For Win/CE|64, make CC just the
+	compiler and move the necessary includes to CFLAGS.
+	(TEA_CONFIG_CFLAGS): Add Solaris 64-bit gcc build support.
+	(TEA_PROG_TCLSH, TEA_PROG_WISH): Allow TCLSH_PROG and WISH_PROG to
+	be set in the env and prevent resetting.
+	(TEA_ADD_LIBS): On Windows using GCC (mingw), convert foo.lib
+	args to -lfoo, for use with mingw.
+		*** POTENTIAL INCOMPATABILITY ***
+	(TEA_CONFIG_CFLAGS): Fix AIX gcc builds to work out-of-box.
+	Bumped TEA to 3.2.
+
+2005-01-27  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4: remove cygpath calls to support msys.
+	Update base CE build assumption to "420,ARMV4,ARM,Pocket PC 2003".
+	Make STLIB_LD use $LINKBIN -lib.
+
+2005-01-25  Daniel Steffen  <das@users.sourceforge.net>
+
+	* tcl.m4 (Darwin): fixed bug with static build linking to dynamic
+	library in /usr/lib etc instead of linking to static library earlier
+	in search path. [Tcl Bug 956908]
+	Removed obsolete references to Rhapsody.
+
+2004-12-29  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4: Updates for VC7 compatibility, fixing CFLAGS and LDFLAGS
+	options, using better default -O levels. [Bug 1092952, 1091967]
+
+2004-12-29  Joe English  <jenglish@users.sourceforge.net>
+
+	* tcl.m4: Do not use ${DBGX} suffix when building
+	shared libraries [patch #1081595, TIP #34]
+
+2004-09-07  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4 (TEA_CONFIG_CFLAGS): support eVC4 Win/CE builds
+
+2004-08-10  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4 (TEA_INIT, TEA_PREFIX): update handling of exec_prefix to
+	work around subdir configures since autoconf only propagates the
+	prefix (not exec_prefix).
+
+2004-07-23  Daniel Steffen  <das@users.sourceforge.net>
+
+	* tcl.m4 (TEA_CONFIG_CFLAGS): Darwin section: brought inline with
+	Tcl 8.5 HEAD config, removed core specific & obsolete settings.
+
+2004-07-22  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4 (TEA_PATH_X): check in TK_DEFS for MAC_OSX_TK to see if
+	we are compiling on Aqua.  Add TEA_WINDOWINGSYSTEM var that
+	reflects 'tk windowingsystem' value.
+
+2004-07-16  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4 (TEA_ENABLE_THREADS): force a threaded build when
+	building against a threaded core.
+	(CFLAGS_WARNING): Remove -Wconversion for gcc builds
+	(TEA_CONFIG_CFLAGS): Reorder configure.in for better 64-bit build
+	configuration, replacing EXTRA_CFLAGS with CFLAGS.  [Bug #874058]
+	Update to latest Tcl 8.5 head config settings.
+	Call this TEA version 3.1.
+
+2004-04-29  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4 (TEA_TCL_64BIT_FLAGS): replace AC_TRY_RUN test with
+	AC_TRY_COMPILE for the long vs. long long check. (kenny)
+
+2004-04-26  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4 (TEA_TCL_64BIT_FLAGS): update against core tcl.m4 to
+	define TCL_WIDE_INT_IS_LONG if 'using long'.
+
+2004-03-19  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4: correct Windows builds getting LDFLAGS info in MAKE_LIB
+
+2004-02-11  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4: correct TCL_INCLUDES for private headers on Windows - it
+	doesn't need the eval.
+
+2004-02-10  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4: don't require TK_INCLUDES and TCL_INCLUDES to have the
+	DIR_NATIVE vars defined when using private headers on unix.
+	Allow $... to TEA_ADD_SOURCES for constructs like
+	TEA_ADD_SOURCES([\$(WIN_OBJECTS)]), that allow the developer to
+	place more in the Makefile.in.
+	tkUnixPort.h checks for HAVE_LIMITS_H, so do both HAVE and
+	CHECK on limits.h
+
+2003-12-10  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* Makefile.in:      added TEA_ADD_LIBS, TEA_ADD_INCLUDES and
+	* configure:        TEA_ADD_CFLAGS to configurable parameters with
+	* configure.in:     PKG_* equivs in the Makefile.  This allows the
+	* tclconfig/tcl.m4: user to worry less about actual magic VAR names.
+	Corrected Makefile.in to note that TEA_ADD_TCL_SOURCES requires
+	exact file names.
+
+2003-12-09  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4: updated OpenBSD support based on [Patch #775246] (cassoff)
+
+2003-12-05  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* configure:
+	* configure.in:
+	* Makefile.in (VPATH): readd $(srcdir) to front of VPATH as the
+	first part of VPATH can get chopped off.
+	Change .c.$(OBJEXT) rule to .c.@OBJEXT@ to support more makes.
+	* tclconfig/tcl.m4: add TEA_ADD_STUB_SOURCES to support libstub
+	generation and TEA_ADD_TCL_SOURCES to replace RUNTIME_SOURCES as
+	the way the user specifies library files.
+
+2003-12-03  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* configure:           Update of TEA spec to (hopefully) simplify
+	* configure.in:        some aspects of TEA by making use of more
+	* Makefile.in:         AC 2.5x features.  Use PACKAGE_NAME (instead
+	* generic/tclsample.c: of PACKAGE) and PACKAGE_VERSION (instead of
+	* tclconfig/tcl.m4:    VERSION) arguments to AC_INIT as the TEA
+	package name and version.
+	Provide a version argument to TEA_INIT - starting with 3.0.
+	Drop all use of interior shell substs that older makefiles didn't
+	like.  Use PKG_* naming convention instead.
+	Move specification of source files and public headers into
+	configure.in with TEA_ADD_SOURCES and TEA_ADD_HEADERS.  These will
+	be munged during ./configure into the right obj file names (no
+	$(SOURCES:.c=.obj) needed).
+	There is almost nothing that should be touched in Makefile.in now
+	for the developer.  May want to add a TEA_ADD_TCL_SOURCES for the
+	RUNTIME_SOURCES that remains.
+	Use SHLID_LD_FLAGS (instead of SHLID_LDFLAGS) as Tcl does.
+	Only specify the user requested LDFLAGS/CFLAGS in the Makefile,
+	don't mention the _OPTIMIZE/_DEBUG variants.
+
+2003-10-15  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4: create a TEA_SETUP_COMPILER_CC the precedes the
+	TEA_SETUP_COMPILER macro.  They are split so the check for CC
+	occurs before any use of CC.  Also add AC_PROG_CPP to the compiler
+	checks.
+
+2003-10-06  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4: Updated for autoconf 2.5x prereq.
+	Where TCL_WIDE_INT_TYPE would be __int64, defer to the code checks
+	in tcl.h, which also handles TCL_LL_MODIFIER* properly.
+
+2003-04-22  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4: correct default setting of ARCH for WinCE builds.
+	Correct \ escaping for CE sed macros.
+
+2003-04-10  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4: replace $(syscal) construct with older `syscall` for
+	systems where sh != bash.
+
+2003-04-09  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4 (TEA_WITH_CELIB): add --enable-wince and --with-celib
+	options for Windows/CE compilation support.  Requires the
+	Microsoft eMbedded SDK and Keuchel's celib emulation layer.
+
+2003-02-18  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4 (TEA_ENABLE_THREADS): Make sure -lpthread gets passed on
+	the link line when checking for the pthread_attr_setstacksize
+	symbol. (dejong)
+
+	* tcl.m4 (TEA_SETUP_COMPILER): added default calls to
+	TEA_TCL_EARLY_FLAGS, TEA_TCL_64BIT_FLAGS,
+	TEA_MISSING_POSIX_HEADERS and TEA_BUGGY_STRTOD.
+
+2003-02-14  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4: correct HP-UX ia64 --enable-64bit build flags
+
+2003-01-29  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4: check $prefix/lib as well as $exec_prefix/lib when
+	looking for tcl|tkConfig.sh, as this check is done before we would
+	set exec_prefix when the user does not define it.
+
+2003-01-21  Mo DeJong  <mdejong@users.sourceforge.net>
+
+	* tcl.m4 (TEA_CONFIG_CFLAGS): Fix build support
+	for mingw, the previous implementation would
+	use VC++ when compiling with mingw gcc. Don't
+	pass -fPIC since gcc always compiles pic code
+	under win32. Change some hard coded cases
+	of gcc to ${CC}.
+
+2002-10-15  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4: move the CFLAGS definition from TEA_ENABLE_SHARED to
+	TEA_MAKE_LIB because setting too early confuses other AC_* macros.
+	Correct the HP-11 SHLIB_LD_LIBS setting.
+
+	* tcl.m4: add the CFLAGS definition into TEA_ENABLE_SHARED and
+	make it pick up the env CFLAGS at configure time.
+
+2002-10-09  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4: add --enable-symbols=mem option to enable TCL_MEM_DEBUG.
+	Improved AIX 64-bit build support, allow it on AIX-4 as well.
+	Enable 64-bit HP-11 compilation with gcc.
+	Enable 64-bit IRIX64-6 cc build support.
+	Correct FreeBSD thread library linkage.
+	Add OSF1 static build support.
+	Improve SunOS-5 shared build SHLIB_LD macro.
+
+2002-07-20  Zoran Vasiljevic  <zoran@archiware.com>
+
+	* tcl.m4: Added MINGW32 to list of systems checked for Windows build.
+	Also, fixes some indentation issues with "--with-XXX" options.
+
+2002-04-23  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4 (TEA_ENABLE_THREADS): added USE_THREAD_ALLOC define to
+	use new threaded allocatory by default on Unix for Tcl 8.4.
+	(TEA_CONFIG_CFLAGS): corrected LD_SEARCH_FLAGS for FreeBSD-3+.
+
+2002-04-22  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4 (TEA_SETUP_COMPILER): removed call to AC_CYGWIN so that
+	we can use autoconf 2.5x as well as 2.13.  This prevents us from
+	being able to warn against the use of cygwin gcc at configure
+	time, but allows autoconf 2.5x, which is what is shipped with most
+	newer systems.
+
+2002-04-11  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4: Enabled COFF as well as CV style debug info with
+	--enable-symbols to allow Dr. Watson users to see function info.
+	More info on debugging levels can be obtained at:
+	http://msdn.microsoft.com/library/en-us/dnvc60/html/gendepdebug.asp
+
+2002-04-03  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4: change all SC_* macros to TEA_*.  The SC_ was for
+	Scriptics, which is no more.  TEA represents a better, independent
+	prefix that won't need changing.
+	Added preliminary mingw gcc support. [Patch #538772]
+	Added TEA_PREFIX macro that handles defaulting the prefix and
+	exec_prefix vars to those used by Tcl if none were specified.
+	Added TEA_SETUP_COMPILER macro that encompasses the AC_PROG_CC
+	check and several other basic AC_PROG checks needed for making
+	executables.  This greatly simplifies user's configure.in files.
+	Collapsed AIX-5 defines into AIX-* with extra checks for doing the
+	ELF stuff on AIX-5-ia64.
+	Updated TEA_ENABLE_THREADS to take an optional arg to allow
+	switching it on by default (for Thread) and add sanity checking to
+	warn the user if configuring threads incompatibly.
+
+2002-03-29  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4: made sure that SHLIB_LDFLAGS was set to LDFLAGS_DEFAULT.
+	Removed --enable-64bit support for AIX-4 because it wasn't correct.
+	Added -MT or -MD Windows linker switches to properly support
+	symbols-enabled builds.
+
+2002-03-28  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4: called AC_MSG_ERROR when SC_TEA_INIT wasn't called first
+	instead of calling it as that inlines it each time in shell code.
+	Changed Windows CFLAGS_OPTIMIZE to use -O2 instead of -Oti.
+	Noted TCL_LIB_VERSIONS_OK=nodots for Windows builds.
+	A few changes to support itcl (and perhaps others):
+	Added support for making your own stub libraries to SC_MAKE_LIB.
+	New SC_PATH_CONFIG and SC_LOAD_CONFIG that take a package name arg
+	and find that ${pkg}Config.sh file.  itk uses this for itcl.
+
+2002-03-27  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4: made SC_LOAD_TKCONFIG recognize when working with a Tk
+	build dir setup.
+	Added EXTRA_CFLAGS and SHLIB_LD_LIBS substs to SC_CONFIG_CFLAGS.
+	Added XLIBSW onto LIBS when it is defined.
+	Remove TCL_LIBS from MAKE_LIB and correctly use SHLIB_LD_LIBS
+	instead to not rely as much on tclConfig.sh cached info.
+	Add TK_BIN_DIR to paths to find wish in SC_PROG_WISH.
+	These move towards making TEA much more independent of *Config.sh.
+
+2002-03-19  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4: corrected forgotten (UN)SHARED_LIB_SUFFIX and
+	SHLIB_SUFFIX defines for Win.
+	(SC_PATH_X): made this only do the check on unix platforms.
+
+2002-03-12  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* README.txt: updated to reflect fewer files
+
+2002-03-06  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* config.guess (removed):
+	* config.sub (removed): removed unnecessary files
+
+	* installFile.tcl (removed):
+	* mkinstalldirs (removed): these aren't really necessary for
+	making TEA work
+
+	* tcl.m4 (SC_PUBLIC_TCL_HEADERS, SC_PUBLIC_TK_HEADERS): don't
+	check /usr(/local)/include for includes on Windows when not using
+	gcc
+
+2002-03-05  Jeff Hobbs  <jeffh@ActiveState.com>
+
+	* tcl.m4: added warnings on Windows, removed RELPATH define and
+	added TCL_LIBS to MAKE_LIB macro.
+
+	This import represents 2.0.0, or a new start at attempting to
+	make TEA much easier for C extension developers.
+
+	**** moved from tclpro project to core tcl project, ****
+	**** renamed to 'tclconfig'                         ****
+
+2001-03-15    Karl Lehenbauer <karl@procplace.com>
+
+	* installFile.tcl: Added updating of the modification time of
+	  the target file whether we overwrote it or decided that it
+	  hadn't changed.  This was necessary for us to be able to
+	  determine whether or not a module install touched the file.
+
+2001-03-08    Karl Lehenbauer <karl@procplace.com>
+
+	* installFile.tcl: Added support for converting new-style (1.1+)
+	  Cygnus drive paths to Tcl-style.
+
+2001-01-15    <brent.welch@interwoven.com>
+
+	* tcl.m4: Added FreeBSD clause.
+
+2001-01-03    <brent.welch@interwoven.com>
+
+	* tcl.m4: Fixed typo in SC_LIB_SPEC where it is checking
+	for exec-prefix.
+
+2000-12-01    <brent.welch@interwoven.com>
+
+	* tcl.m4: Concatenated most of the Ajuba acsite.m4 file
+	so we don't need to modify the autoconf installation.
+	* config.guess:
+	* config.sub:
+	* installFile.tcl:
+	Added files from the itcl config subdirectory,
+	which should go away.
+
+2000-7-29    <welch@ajubasolutions.com>
+
+	* Fixed the use of TCL_SRC_DIR and TK_SRC_DIR within
+	TCL_PRIVATE_INCLUDES and TK_PRIVATE_INCLUDES to match their recent
+	change from $(srcdir) to $(srcdir)/..

+# Running socket tests with a remote server:
+# ------------------------------------------
+# 
+# Some tests in socket.test depend on the existence of a remote server to
+# which they connect. The remote server must be an instance of tcltest and it
+# must run the script found in the file "remote.tcl" in this directory. You
+# can start the remote server on any machine reachable from the machine on
+# which you want to run the socket tests, by issuing:
+# 
+#     tcltest remote.tcl -port 8048	# Or choose another port number.
+# 
+# If the machine you are running the remote server on has several IP
+# interfaces, you can choose which interface the server listens on for
+# connections by specifying the -address command line flag, so:
+# 
+#     tcltest remote.tcl -address your.machine.com
+# 
+# These options can also be set by environment variables. On Unix, you can
+# type these commands to the shell from which the remote server is started:
+# 
+#     shell% setenv serverPort 8048
+#     shell% setenv serverAddress your.machine.com
+# 
+# and subsequently you can start the remote server with:
+# 
+#     tcltest remote.tcl
+# 
+# to have it listen on port 8048 on the interface your.machine.com.
+#     
+# When the server starts, it prints out a detailed message containing its
+# configuration information, and it will block until killed with a Ctrl-C.
+# Once the remote server exists, you can run the tests in socket.test with
+# the server by setting two Tcl variables:
+# 
+#     % set remoteServerIP <name or address of machine on which server runs>
+#     % set remoteServerPort 8048
+# 
+# These variables are also settable from the environment. On Unix, you can:
+# 
+#     shell% setenv remoteServerIP machine.where.server.runs
+#     shell% setenv remoteServerPort 8048
+# 
+# The preamble of the socket.test file checks to see if the variables are set
+# either in Tcl or in the environment; if they are, it attempts to connect to
+# the server. If the connection is successful, the tests using the remote
+# server will be performed; otherwise, it will attempt to start the remote
+# server (via exec) on platforms that support this, on the local host,
+# listening at port 8048. If all fails, a message is printed and the tests
+# using the remote server are not performed.

+<h3><a name="DESCRIPTION">DESCRIPTION</a></h3>
+
+<p>This extension provides a generic binding to <a
+href="http://www.openssl.org/">OpenSSL</a>, utilizing the
+<strong>Tcl_StackChannel</strong>
+API for Tcl 8.2 and higher. The sockets behave exactly the same
+as channels created using Tcl's built-in <strong>socket</strong>
+command with additional options for controlling the SSL session.
+To use TLS with an earlier version of Tcl than 8.4, please obtain
+TLS 1.3.
+</p>
+
+<h3><a name="COMMANDS">COMMANDS</a></h3>
+
+<p>Typically one would use the <strong>tls::socket </strong>command
+which provides compatibility with the native Tcl <strong>socket</strong>
+command. In such cases <strong>tls::import</strong> should not be
+used directly.</p>
+
+<dl>
+    <dt><a name="tls::init"><b>tls::init </b><i>?options?</i></a></dt>
+    <dd>This routine sets the default options used by <strong>tls::socket</strong>
+        and is <em>optional</em>. If you call <strong>tls::import</strong>
+        directly this routine has no effect. Any of the options
+        that <strong>tls::socket</strong> accepts can be set
+        using this command, though you should limit your options
+        to only TLS related ones.</dd>

+<h3><a name="CALLBACK OPTIONS">CALLBACK OPTIONS</a></h3>
+
+<p>
+As indicated above, individual channels can be given their own callbacks
+to handle intermediate processing by the OpenSSL library, using the
+<em>-command</em> and <em>-password</em> options passed to either of
+<strong>tls::socket</strong> or <strong>tls::import</strong>.
+</p>
+
+<blockquote>
+<dl>
+
+    <dt><strong>-command</strong> <em>callback</em></dt>
+    <dd>
+	Invokes the specified <em>callback</em> script at
+	several points during the OpenSSL handshake.
+	Except as indicated below, values returned from the
+	callback are ignored.
+	Arguments appended to the script upon callback take one of the
+	following forms:
+
+	<br>
+	<br>
+
+	<dl>
+
+<!--	This form of callback is disabled.
+
+	<dt>
+	  <strong>error</strong> <em>channel message</em>
+	</dt>
+	<dd>
+	  The <em>message</em> argument contains an error message generated
+	  by the OpenSSL function
+	  <code>ERR_reason_error_string()</code>.
+	</dd>
+
+	<br>
+-->
+
+	<dt>
+	  <strong>info</strong> <em>channel major minor message</em>
+	</dt>
+	<dd>
+	  This form of callback is invoked by the OpenSSL function
+	  <code>SSL_CTX_set_info_callback()</code>.
+	  <br>
+	  The <em>major</em> and <em>minor</em> arguments are used to
+	  represent the state information bitmask.
+	  <dl>
+	  <dt>Possible values for <em>major</em> are:</dt>
+	  <dd><code>handshake, alert, connect, accept</code>.</dd>
+	  <dt>Possible values for <em>minor</em> are:</dt>
+	  <dd><code>start, done, read, write, loop, exit</code>.</dd>
+	  </dl>
+	  The <em>message</em> argument is a descriptive string which may
+	  be generated either by
+	  <code>SSL_state_string_long()</code> or by
+	  <code>SSL_alert_desc_string_long()</code>,
+	  depending on context.
+	</dd>
+
+	<br>
+
+	<dt>
+	  <strong>verify</strong> <em>channel depth cert status error</em>
+	</dt>
+	<dd>
+	  This form of callback is invoked by the OpenSSL function
+	  <code>SSL_set_verify()</code>.
+	  <br>
+	  The <em>depth</em> argument is an integer representing the
+	  current depth on the certificate chain, with
+	  <code>0</code> as the subject certificate and higher values
+	  denoting progressively more indirect issuer certificates.
+	  <br>
+	  The <em>cert</em> argument is a list of key-value pairs similar
+	  to those returned by
+	  <a href="#tls::status"><strong>tls::status</strong></a>.
+	  <br>
+	  The <em>status</em> argument is an integer representing the
+	  current validity of the certificate.
+	  A value of <code>0</code> means the certificate is deemed invalid.
+	  A value of <code>1</code> means the certificate is deemed valid.
+	  <br>
+	  The <em>error</em> argument supplies the message, if any, generated
+	  by
+	  <code>X509_STORE_CTX_get_error()</code>.
+	  <br>
+	  <br>
+	  The callback may override normal validation processing by explicitly
+	  returning one of the above <em>status</em> values.
+	</dd>
+
+	</dl>
+    </dd>
+
+    <br>
+
+    <dt><strong>-password</strong> <em>callback</em></dt>
+    <dd>
+	Invokes the specified <em>callback</em> script when OpenSSL needs to
+	obtain a password.  The callback should return a string which
+	represents the password to be used.
+	No arguments are appended to the script upon callback.
+    </dd>
+</dl>
+</blockquote>
+
+<p>
+Reference implementations of these callbacks are provided in the
+distribution as <strong>tls::callback</strong> and
+<strong>tls::password</strong> respectively.  Note that these are
+<em>sample</em> implementations only.  In a more realistic deployment
+you would specify your own callback scripts on each TLS channel
+using the <em>-command</em> and <em>-password</em> options.
+</p>
+
+<p>
+The default behavior when the <em>-command</em> option is not specified is for
+TLS to process the associated library callbacks internally.
+The default behavior when the <em>-password</em> option is not specified is for
+TLS to process the associated library callbacks by attempting to call
+<strong>tls::password</strong>.
+The difference between these two behaviors is a consequence of maintaining
+compatibility with earlier implementations.
+</p>
+
+<p>
+The <strong>tls::debug</strong> variable provides some additional
+control over these reference callbacks.  Its value is zero by default.
+Higher values produce more diagnostic output, and will also force the
+verify method in <strong>tls::callback</strong> to accept the
+certificate, even when it is invalid.
+</p>
+
+<p>
+<em>
+The use of the reference callbacks <strong>tls::callback</strong> and
+<strong>tls::password</strong> is not recommended.  They may be removed
+from future releases.
+</em>
+</p>
+
+<p>
+<em>
+The use of the variable <strong>tls::debug</strong> is not recommended.
+It may be removed from future releases.
+</em>

+<h3><a name="HTTPS EXAMPLE">HTTPS EXAMPLE</a></h3>
+
+<p>This example uses a sample server.pem provided with the TLS release,
+courtesy of the <strong>OpenSSL</strong> project.</p>
+
+<pre><code>
+package require http
+package require tls
+
+http::register https 443 [list ::tls::socket -require 1 -cafile ./server.pem]
+
+set tok [http::geturl https://developer.netscape.com/]
+</code></pre>
+
+<h3><a name="SPECIAL CONSIDERATIONS">SPECIAL CONSIDERATIONS</a></h3>
+
+<p>The capabilities of this package can vary enormously based
+upon how your OpenSSL library was configured and built. At the
+most macro-level OpenSSL supports a &quot;no patents&quot; build,
+which disables RSA, IDEA, RC(2,4,5) and SSL2 - if your OpenSSL is
+configured this way then you will need to build TLS with the
+-DNO_PATENTS option - and the resultant module will function
+correctly and also support ADH certificate-less encryption,
+however you will be unable to utilize this to speak to normal Web
+Servers, which typically require RSA support. Please see <a
+href="http://www.openssl.org/">http://www.openssl.org/</a> for
+more information on the whole issue of patents and US export
+restrictions. </p>

+#-------------------------------------------------------------------------
+
+# Check to see we are configured to build with MSVC (MSDEVDIR or MSVCDIR)
+# or with the MS Platform SDK (MSSDK). Visual Studio .NET 2003 and 2005 define
+# VCINSTALLDIR instead. The MSVC Toolkit release defines yet another.
+!if !defined(MSDEVDIR) && !defined(MSVCDIR) && !defined(MSSDK) && !defined(VCINSTALLDIR) && !defined(VCToolkitInstallDir)
+MSG = ^
+You need to run vcvars32.bat from Developer Studio or setenv.bat from the^
+Platform SDK first to setup the environment.  Jump to this line to read^
+the build instructions.
+!error $(MSG)
+!endif
+
+#------------------------------------------------------------------------------
+# HOW TO USE this makefile:
+#
+# 1)  It is now necessary to have %MSVCDir% set in the environment.  This is
+#     used  as a check to see if vcvars32.bat had been run prior to running
+#     nmake or during the installation of Microsoft Visual C++, MSVCDir had
+#     been set globally and the PATH adjusted.  Either way is valid.
+#
+#     You'll need to run vcvars32.bat contained in the MsDev's vc(98)/bin
+#     directory to setup the proper environment, if needed, for your current
+#     setup.  This is a needed bootstrap requirement and allows the swapping of
+#     different environments to be easier.
+#
+# 2)  To use the Platform SDK (not expressly needed), run setenv.bat after
+#     vcvars32.bat according to the instructions for it.  This can also turn on
+#     the 64-bit compiler, if your SDK has it.
+#
+# 3)  Targets are:
+#	all       -- Builds everything.
+#       <project> -- Builds the project (eg: nmake sample)
+#	test      -- Builds and runs the test suite.
+#	install   -- Installs the built binaries and libraries to $(INSTALLDIR)
+#		     in an appropriate subdirectory.
+#	clean/realclean/distclean -- varying levels of cleaning.
+#
+# 4)  Macros usable on the commandline:
+#	INSTALLDIR=<path>
+#		Sets where to install Tcl from the built binaries.
+#		C:\Progra~1\Tcl is assumed when not specified.
+#
+#	OPTS=static,msvcrt,staticpkg,threads,symbols,profile,loimpact,none
+#		Sets special options for the core.  The default is for none.
+#		Any combination of the above may be used (comma separated).
+#		'none' will over-ride everything to nothing.
+#
+#		static  =  Builds a static library of the core instead of a
+#			   dll.  The shell will be static (and large), as well.
+#		msvcrt  =  Effects the static option only to switch it from
+#			   using libcmt(d) as the C runtime [by default] to
+#			   msvcrt(d). This is useful for static embedding
+#			   support.
+#		staticpkg = Effects the static option only to switch
+#			   tclshXX.exe to have the dde and reg extension linked
+#			   inside it.
+#		nothreads = Turns off multithreading support (not recommended)
+#		thrdalloc = Use the thread allocator (shared global free pool).
+#		symbols =  Adds symbols for step debugging.
+#		profile =  Adds profiling hooks.  Map file is assumed.
+#		loimpact =  Adds a flag for how NT treats the heap to keep memory
+#			   in use, low.  This is said to impact alloc performance.
+#
+#	STATS=memdbg,compdbg,none
+#		Sets optional memory and bytecode compiler debugging code added
+#		to the core.  The default is for none.  Any combination of the
+#		above may be used (comma separated).  'none' will over-ride
+#		everything to nothing.
+#
+#		memdbg   = Enables the debugging memory allocator.
+#		compdbg  = Enables byte compilation logging.
+#
+#	MACHINE=(IX86|IA64|ALPHA|AMD64)
+#		Set the machine type used for the compiler, linker, and
+#		resource compiler.  This hook is needed to tell the tools
+#		when alternate platforms are requested.  IX86 is the default
+#		when not specified. If the CPU environment variable has been
+#		set (ie: recent Platform SDK) then MACHINE is set from CPU.
+#
+#	TMP_DIR=<path>
+#	OUT_DIR=<path>
+#		Hooks to allow the intermediate and output directories to be
+#		changed.  $(OUT_DIR) is assumed to be 
+#		$(BINROOT)\(Release|Debug) based on if symbols are requested.
+#		$(TMP_DIR) will de $(OUT_DIR)\<buildtype> by default.
+#
+#	TESTPAT=<file>
+#		Reads the tests requested to be run from this file.
+#
+#	CFG_ENCODING=encoding
+#		name of encoding for configuration information. Defaults
+#		to cp1252
+#
+# 5)  Examples:
+#
+#	Basic syntax of calling nmake looks like this:
+#	nmake [-nologo] -f makefile.vc [target|macrodef [target|macrodef] [...]]
+#
+#                        Standard (no frills)
+#       c:\tcl_src\win\>c:\progra~1\micros~1\vc98\bin\vcvars32.bat
+#       Setting environment for using Microsoft Visual C++ tools.
+#       c:\tcl_src\win\>nmake -f makefile.vc all
+#       c:\tcl_src\win\>nmake -f makefile.vc install INSTALLDIR=c:\progra~1\tcl
+#
+#                         Building for Win64
+#       c:\tcl_src\win\>c:\progra~1\micros~1\vc98\bin\vcvars32.bat
+#       Setting environment for using Microsoft Visual C++ tools.
+#       c:\tcl_src\win\>c:\progra~1\platfo~1\setenv.bat /pre64 /RETAIL
