@NAME : dump_acr_nema.c
@DESCRIPTION: Program to dump the contents of an acr-nema file.
@METHOD :
@GLOBALS :
@CREATED : November 24, 1993 (Peter Neelin)
@MODIFIED :
* $Log: dump_acr_nema.c,v $
* Revision 6.7 2005/03/11 22:19:59 bert
* add '-t' option to parse files which contain lists of field names with corresponding group and element id's.
*
* Revision 6.6 2004/10/29 13:08:41 rotor
* * rewrote Makefile with no dependency on a minc distribution
* * removed all references to the abominable minc_def.h
* * I should autoconf this really, but this is old code that
* is now replaced by Jon Harlaps PERL version..
*
* Revision 6.5 2001/11/08 14:17:05 neelin
* Added acr_test_dicom_file to allow reading of DICOM part 10 format
* files. This function also calls acr_test_byte_order to set up the stream
* properly and can be used as a direct replacement for that function.
* This set of changes does NOT include the ability to write part 10 files.
*
* Revision 6.4 2000/05/01 17:54:45 neelin
* Fixed handling of test for byte order.
*
* Revision 6.3 2000/05/01 13:59:55 neelin
* Added -e option to allow reading data streams with explicit VR.
*
* Revision 6.2 2000/04/28 15:02:01 neelin
* Added more general argument processing (but not with ParseArgv).
* Added support for ignoring non-fatal protocol errors.
* Added support for user-specified byte-order.
*
* Revision 6.1 1999/10/29 17:51:51 neelin
* Fixed Log keyword
*
* Revision 6.0 1997/09/12 13:23:59 neelin
* Release of minc version 0.6
*
* Revision 5.0 1997/08/21 13:25:00 neelin
* Release of minc version 0.5
*
* Revision 4.1 1997/07/10 17:14:38 neelin
* Added more status codes and function to return status string.
*
* Revision 4.0 1997/05/07 20:01:23 neelin
* Release of minc version 0.4
*
* Revision 3.1 1997/04/21 20:21:09 neelin
* Updated the library to handle dicom messages.
*
* Revision 3.0 1995/05/15 19:32:12 neelin
* Release of minc version 0.3
*
* Revision 2.1 1995/02/06 14:12:55 neelin
* Added argument to specify maximum group id to dump.
*
* Revision 2.0 94/09/28 10:36:09 neelin
* Release of minc version 0.2
*
* Revision 1.6 94/09/28 10:35:53 neelin
* Pre-release
*
* Revision 1.5 94/05/18 08:48:05 neelin
* Changed some ACR_OTHER_ERROR's to ACR_ABNORMAL_END_OF_OUTPUT.
*
* Revision 1.4 94/04/07 10:04:58 neelin
* Added status ACR_ABNORMAL_END_OF_INPUT and changed some ACR_PROTOCOL_ERRORs
* to that or ACR_OTHER_ERROR.
* Added #ifdef lint to DEFINE_ELEMENT.
*
* Revision 1.3 93/11/25 10:35:33 neelin
* Added byte-order test and file free.
*
* Revision 1.2 93/11/24 12:05:00 neelin
* Write output to stdout instead of stderr.
*
* Revision 1.1 93/11/24 11:25:01 neelin
* Initial revision
