+
+#------------------------------------------------------------------------------
+# 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
