20020428 DAC

This is a very crude patch to the well known tcpdump tool to make it
try and detect DICOM packets and dump their contents.

It is very limited in that it does not maintain state between packets. I.e.
if there is something useful in the first packet dumped then it is helpful,
otherwise the successive packets are treated as any other (non-DICOM) packet.

To apply this patch:

	fetch, uncompress, untar, configure and compile libpcap-0.7.1
	fetch, uncompress, untar tcpdump-3.7.1

	cd tcpdump-3.7.1
	patch -p1 <../tcpdump-3.7.1.dicom.patch.20020428 

Further information may be found in tcpdump-3.7.1/tcpdump.dicom.README once the
patch has been applied.
