 $Log: cmdlog.c,v $

 Revision 1.1.1.1  2003/11/04 23:34:56  mjames

 Imported into local repositrory

 Revision 1.14  2002/01/03 16:36:57  mjames

 Method of accessing Vertical version changed to avoid

 global variable

 Also made DLL exportable function

 Revision 1.13  2001/12/13 22:16:16  mjames

 Using #ident with header to identify file

 Revision 1.12  2001/11/19 10:41:52  mjames

 Merged back DTC release

 Revision 1.11.2.1  2001/11/16 15:09:42  mjames

 Added log silent and log verbose commands, along with corresponding

 low level calls.

 Revision 1.11  2001/10/31 16:24:32  mjames

 Changing the error message fprintf to use a format specifier instead of the

 string itself.

 Revision 1.10  2001/07/09 15:48:07  mjames

 Placed the version string in an independent file to save time on building

 all of the variants of Vertical

 Revision 1.9  2001/07/09 15:35:18  mjames

 Corrected argument counting bug in log lfile command

 Used correct version string extracted from version.c

 Revision 1.8  2001/06/19 05:24:57  mjames

 Created a trap_fopen to overcome trying to write to read only files.

 If this attempted in NT the file can be opened but not written to.

 Revision 1.7  2001/06/06 12:10:25  mjames

 Move from HPUX

 Revision 1.6  2001/02/21 16:37:32  mjames

 Provided a new method of defining port maps with VHDL which allows for short

 cut definitions.

 Cleaned up TCL/Tk interfacing issues

 Revision 1.5  2001/02/01 21:41:44  mjames

 Made the code begin to compile without TCL/TK

 Revision 1.4  2001/01/26 21:50:10  mjames

 Managed to get vertical non TCL to compile again

 Conversion to argv, argc[] mode of operation continues

 Revision 1.3  2001/01/04 21:26:54  mjames

 Modifications to add in the TCL style

 argument list to all of the functions

 .

 Revision 1.2  2001/01/02 07:53:51  mjames

 Made changes to allow for interface with TCL/Tk

 Revision 1.1.1.1  2000/10/19 21:58:35  mjames

 Mike put it here
