20// The TROOT object is the entry point to the system. //
21// The single instance of TROOT is accessible via the global gROOT. //
22// Using the gROOT pointer one has access to basically every object //
23// created in a ROOT based program. The TROOT object is essentially a //
24// container of several lists pointing to the main ROOT objects. //
