I want to use the open source version of the RhoMobile Suite in eclipse.

eclipse --> Help –> Install New Software

In the Install popup, add the RhoStudio update site:
Enter name: RhoStudio
Enter location: http://rhostudio.rhomobile.com

but cause error:
Could not find http://rhostudio.rhomobile.com

Where is correct url?
or
Where is rhostudio zip file for eclipse plugin?

Thanks.
