// This macro being called at the end of ROOT session cleares all the

// ROOT lists. In result, no ROOT objects will be deleted after ".q"

// It is made especially to avoid deleting of TGeoManager which, due to bad

// design, often leads to crash, which in its turn, is not always acceptable (VP)
