27// KPROCESS -- A class for handling child processes in KDE without
28// having to take care of Un*x specific implementation details
29//
30// version 0.3.1, Jan 8th 1998
31//
32// (C) Christian Czezatke
33// e9025461@student.tuwien.ac.at
34//
35// Changes:
36//
37// March 2nd, 1998: Changed parameter list for KShellProcess:
38// Arguments are now placed in a single string so that
39// <shell> -c <commandstring> is passed to the shell
40// to make the use of "operator<<" consistent with KProcess
41//
42//
43// Ported by Holger Freyther
44// <zekce> Harlekin: oprocess and say it was ported to Qt by the Opie developers an Qt 2
