MapGuide Web Studio

[Nicol Hermann]

Dear List,

as i could read in the release notes
(https://www.osgeo.org/files/documents/12/236/releasenotes.html)
MapGuide Web Studio should be part of the new MapGuide Open Source 1.0.1
Release.
I downloaded the source code of MGOS from
https://mapguide.osgeo.org/files/documents/12/233/mapguide-1.0.1.tar.gz
but i am unable to find any hint to webstudio.
Where can i find the files in the source tree (before the installation)?
I read a posting that the files should be located in
<mgos_installdir>/webserverextensions/www/webstudio
after the installation but there is no such directory in my
installation. Do i miss something?

Many thanks 
Nicol
