 Usage:
   vccexe [options] [compileroptions]
 Options:
+  --vcvarsall:<path>  Path to the Developer Command Prompt utility vcvarsall.bat that selects
+                      the appropiate devlopment settings.
+                      Usual path for Visual Studio 2015 and below:
+                        %VSInstallDir%\VC\vcvarsall
+                      Usual path for Visual Studio 2017 and above:
+                        %VSInstallDir%\VC\Auxiliary\Build\vcvarsall
+  --command:<exec>    Specify the command to run once the development environment is loaded.
+                      <exec> can be any command-line argument. Any arguments not recognized by vccexe
+                      are passed on as arguments to this command.
+                      cl.exe is invoked by default if this argument is omitted.
   --platform:<arch>   Specify the Compiler Platform Tools architecture
                       <arch>: x86 | amd64 | arm | x86_amd64 | x86_arm | amd64_x86 | amd64_arm
-  --winstore          Use Windows Store (rather than desktop) development tools
+                      Values with two architectures (like x86_amd64) specify the architecture
+                      of the cross-platform compiler (e.g. x86) and the target it compiles to (e.g. amd64).
+  --sdktype:<type>    Specify the SDK flavor to use. Defaults to the Desktop SDK.
+                      <type>: {empty} | store | uwp | onecore
   --sdkversion:<v>    Use a specific Windows SDK version:
                       <v> is either the full Windows 10 SDK version number or 
                       "8.1" to use the windows 8.1 SDK
 
 Other command line arguments are passed on to the
-Microsoft C/C++ compiler for the specified SDK toolset
+secondary command specified by --command or to the
+Microsoft (R) C/C++ Optimizing Compiler if no secondary
+command was specified
