+# GetMSVCVersion
+# --------------
+#
+#
+#
+# get_msvc_major_version(<var>)
+# get_msvc_minor_version(<var>)
+# get_msvc_combined_major_minor_version(<var>)
+# get_msvc_major_minor_version(<major_var> <minor_var>)
+# get_msvc_unique_decimal_version(<var>)
+#
+# This family of functions is designed to be used to convert
+# MSVC_VERSION from the compiler version number to the Visual Studio
+# decimal version number (2012 is 11.0, 2015 is 14.0). All take a name
+# of a variable in <var> to return their results in.
+#
+# Consider Visual Studio 2013, which reports 1800 in MSVC_VERSION (and
+# the _MSC_VER preprocessor macro). It is also known as VS 12 or 12.0.
+# (Minor versions are rarely used, except in the case of 7.1 aka
+# VS.NET 2003) The functions would return this output for 2013:
+#
+# get_msvc_major_version: 12
+# get_msvc_minor_version: 0
+# get_msvc_combined_major_minor_version: 120
+# get_msvc_major_minor_version: 12 in <major_var>, 0 in <minor_var>
+# get_msvc_unique_decimal_version: 12  (this returns with a decimal and
+# minor when needed to be precise, e.g. 7.1)
+#
+# The variable is not modified if not building with MSVC.
