41 // G4VBasicShell : a base class to extract common things to various
42 // sessions.
43 //
44 // It handles "seek" completion logic, help logic.
45 // VBasicShell handles also commands like "cd, ls, pwd"
46 // without passing by a Geant4 "intercom" command. This feature,
47 // which is similar to a UNIX shell one, had given.
48 // its name to the class.
