+#	Microsoft Visual C++ makefile for use with nmake.exe v1.62+ (VC++ 5.0+)
+#
+# This makefile is based upon the Tcl 8.6 Makefile.vc and modified to 
+# make it suitable as a general package makefile. Look for the word EDIT
+# which marks sections that may need modification. As a minumum you will
+# need to change the PROJECT, DOTVERSION and DLLOBJS variables to values
+# relevant to your package.

+MSG = ^
+You need to run vcvars32.bat from Developer Studio or setenv.bat from the^

+
+#------------------------------------------------------------------------------
+# HOW TO USE this makefile:
+#
+# 1)  It is now necessary to have MSVCDir, MSDevDir or MSSDK 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=loimpact,msvcrt,nothreads,pdbs,profile,static,symbols,unchecked,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.
+#
+#		loimpact = Adds a flag for how NT treats the heap to keep memory
+#			   in use, low.  This is said to impact alloc performance.
+#		msvcrt  =  Affects 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.
+#		nothreads = Turns off multithreading support (not recommended)
+#		static  =  Builds a static library of the core instead of a
+#			   dll.  The shell will be static (and large), as well.
+#		pdbs     = Build detached symbols for release builds.
+#		profile  = Adds profiling hooks.  Map file is assumed.
+#		symbols  = Debug build. Links to the debug C runtime, disables
+#			   optimizations and creates pdb symbols files.
+#		unchecked = Allows a symbols build to not use the debug
+#			   enabled runtime (msvcrt.dll not msvcrtd.dll
+#			   or libcmt.lib not libcmtd.lib).
+#
+#	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.
+#
+#	CHECKS=64bit,fullwarn,nodep,none
+#		Sets special macros for checking compatability.
+#
+#		64bit    = Enable 64bit portability warnings (if available)
+#		fullwarn = Builds with full compiler and link warnings enabled.
+#			    Very verbose.
+#		nodep	 = Turns off compatability macros to ensure Tk isn't
+#			    being built with deprecated functions.
+#
+#	MACHINE=(ALPHA|AMD64|IA64|IX86)
+#		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.
+#
+# 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
+#       Targeting Windows pre64 RETAIL
+#       c:\tcl_src\win\>nmake -f makefile.vc MACHINE=IA64
