History: Query Ogre Version

            {maketoc}

!!About "Query Ogre Version"
The following tool is designed for Windows (it has been tested on Windows XP). 
It adds a shell extension under the explorer and allows you to query the version of Ogre, the file (or the directory) is belong to.
Once you have merged the .reg file, you can right click a file (or a directory) and select the "Query Ogre Version" entry.
