     91On success, by starting root in your build directory, you should see a message like
     92{{{

     97Welcome to the Mars Root environment.

     102Be aware that it might be slightly different for different versions (in particular of root).

     104You should not be able to use Mars.
     105
     106How does that work? When you start root in your build directory, it reads `.rootrc` in your build directory. This file points to `rootlogon.C` in your build directory. This macro is executed when on root startup and loads the shared object `lib/libmars.so`. As all this uses absoluet paths, you could even move `.rootrc` into your home directory and get the Mars environment no matter where you start root. As this works only with absolute paths, you might not change or rename the build directory without changing those files.
