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