3/// Script drawing a detector geometry (here D0).
4///
5/// by default the geometry is drawn using the GL viewer
6/// Using the TBrowser, you can select other components
7/// if the file containing the geometry is not found in the local
8/// directory, it is automatically read from the ROOT web site.
9/// - run with `.x geomD0.C` top level detectors are transparent
10/// - or `.x geomD0.C(1)` top level detectors are visible
