:::
::: PURPOSE:    This script can be used to run the vcvars32.bat/vcvarsall.bat
:::             from any of the existing Visual C++ versions starting with .NET
:::             (2002) through 2022 or versions (or a single version) given on
:::             the command line.
:::             The script will try to find the newest installed VC version by
:::             iterating over the space-separated (descending) list of versions
:::             in the variable SUPPORTED_VC below, by default.
:::             Call it from another script and after that you will have NMAKE,
:::             DEVENV.EXE and friends available without having to hardcode
:::             their paths into a script or makefile.
