If you have already installed the VS SDK you won´t get this issues mentioned below
	- when I try to open the VSPackage it shows me that it is incompatible
	- try to build the project
		Error	12	The imported project "C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v12.0\VSSDK\Microsoft.VsSDK.targets"
		was not found. Confirm that the path in the <Import> declaration is correct,
		and that the file exists on disk.
		C:\VersionOne.VisualStudio.VSPackage\VersionOne.VisualStudio.VSPackage.csproj	441	3
		VersionOne.VisualStudio.Tests

solution:
 -I downloaded from Ms (http://www.microsoft.com/visualstudio/eng/downloads)
 -modify the manifest file,by adding this line
	<InstallationTarget Version="[12.0,13.0)" Id="Microsoft.VisualStudio.Ultimate" /> and it allows me to install the plug in on the
			vs 2013
NOTE: If you are using some other version than Ultimate, you should add it a new line with the corresponding info.
  <InstallationTarget Version="[12.0,13.0)" Id="Microsoft.VisualStudio.Ultimate" />
  <InstallationTarget Version="[12.0,13.0)" Id="Microsoft.VisualStudio.Pro" />
  <InstallationTarget Version="[12.0,13.0)" Id="Microsoft.VisualStudio.Premium" />

-when trying to install trows me an error see also this reference(http://stackoverflow.com/questions/18095344/how-to-solve-microsoft-visualstudio-extensionmanager-missingreferencesexception)
-remove this line from manifest
  <Dependency d:Source="Manual" Id="Microsoft.VisualStudio.MPF" DisplayName="Visual Studio MPF" Version="10.0" d:InstallSource="Manual" />
