-//  KPROCESS -- A class for handling child processes in KDE without
-//  having to take care of Un*x specific implementation details
-//
-//  version 0.3.1, Jan 8th 1998
-//
-//  (C) Christian Czezatke
-//  e9025461@student.tuwien.ac.at
-//
-// Changes:
-//
-// March 2nd, 1998: Changed parameter list for KShellProcess:
-//   Arguments are now placed in a single string so that
-//   <shell> -c <commandstring> is passed to the shell
-//   to make the use of "operator<<" consistent with KProcess
