-// KPROCESS -- A class for handling child processes in KDE without

-//
-// 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
-//
-//
-// Ported by Holger Freyther
-// <zekce> Harlekin: oprocess and say it was ported to Qt by the Opie developers an Qt 2
