Not really the last vsvars32 you will ever need

I took Peter avise and for a while I’ve been using Chris’s vsvars32, however it had some drawbacks,

1. It did not work from a 64bit PowerShell

2. For some reason Get-Batchfile did not work for me, I had to modify to call “echo” explicitly.

I also added a helper VsInstallDir and a alias for devenv.

 Enjoy,

        $p, $v = $_.split(’=')

        Set-Item -path env:$p -value $v

    }

set-alias devenv ((VsInstallDir)+”\devenv.exe”) -scope global
