Message:

1998-04-16  Olaf Bachmann  <obachman@mathematik.uni-kl.de>

	* MP_Util.c (IMP_GetCmdlineArg): Allow long option names

	* MP_TcpTransp.c (open_tcp_launch_mode): When long option
names
	were used for specification of MPapplication, use long option
	names for MP options which are appended to application.
