+The nmake that comes with Visual C++ will suffice for building. Visual C
+requires that certain things be set up in the console before Visual C will
+sucessfully run. To make a console box be able to run the C compiler, you will
+need to beforehand, run the C<vcvars32.bat> file to compile for x86-32 and for
+x86-64 C<vcvarsall.bat x64> or C<vcvarsamd64.bat>. On a typical install of a
+Microsoft C compiler product, these batch files will already be in your C<PATH>
+environment variable so you may just type them without an absolute path into
+your console. If you need to find the absolute path to the batch file, it is
+usually found somewhere like C:\Program Files\Microsoft Visual Studio\VC98\Bin.
+With some newer Micrsoft C products (released after ~2004), the installer will
+put a shortcut in the start menu to launch a new console window with the
+console already set up for your target architecture (x86-32 or x86-64 or IA64).
+With the newer compilers, you may also use the older batch files if you choose
+so.
