How to build documentation with Doxygen from an msbuild script

doxygen-snippet.msbuild

  <PropertyGroup>
    <DocDirectory>..\Documentation\</DocDirectory>
	<Doxyfile>..\Doxyfile</Doxyfile>
  </PropertyGroup>
  <Target Name="Doxygen">
    <MakeDir Directories="$(DocDirectory)" />
    <Exec Command="doxygen.exe $(Doxyfile)" />
  </Target>
  <Target Name="DoxyClean">
	  <RemoveDir Directories="$(DocDirectory)\html" />
	  <RemoveDir Directories="$(DocDirectory)\latex" />
	  <Delete Files="$(DocDirectory)\*.tmp" />
  </Target>
  <PropertyGroup>  
    <BuildDependsOn>  
        $(BuildDependsOn);  
        Doxygen  
    </BuildDependsOn>  
  </PropertyGroup> 
  <PropertyGroup>  
    <CleanDependsOn>  
        $(CleanDependsOn);  
        DoxyClean  
    </CleanDependsOn>  
  </PropertyGroup> 

Yes, I loathe the Microsoft toolchain. But if one has to use it one might as well get good at it.
