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