IRIS seed output writer, "pod".

Version 3.15:
pod now supports multiple data record lengths. 
Now compiled for solaris an sunos. Rename either pod_sunos
or pod_solaris as pod and place in your path.


Version 3.0:

This version of pod, version 3.0, has a somewhat differing directory
organization than previous versions. This new organization was needed 
because version 3.0 supports multiple stations of the same name but 
differing networks.

The new "harvest" directory looks like, as an example:
				
				HAR000
			-------------------------
	ANMO.II  BAR.G   PFO.II CCM.IU   COL.IU   PFO.TS DGR.IU   H.A  ISA.TS
	   |    				     |
    ----------------       		    -------------------
   B050  BHE  BHN  BHZ  		    B050  BHE  BHN  BHZ  


The old version had a "harvest directory structure which looked like:

				 HAR000 
                ------------------------- 
 		SRAR##      H.A    SWMQ##
		  |                  |
	-----------------       ----------------
B050  B051  CBHE  CBHN		B050  B051  CBHE  CBHN
					

Notice: 
	no more 'S' for 1st character of station directory name.
	no more '##' filler in station name.
	added network code in station name.
	no more 'C' for 1st character in channel directory name.

The 'data_files' directory remains the same, as pod knows which network is
which because the network code is part of the file name.

The pod program uses the network code as entered in the request file as the
starting point. 

Example request file:

BAR     G       BHN     2.0000E+01      C       001     1993,203                1993,204                0000000100      0000000100      01932   G       E       BAR.G.BHN.93.203                HAR000                          BW      1993,203,06:28:30       1993,203,07:08:29     

BAR     TS      BHZ     2.0000E+01      C       001     1993,203                1993,204                0000000100      0000000100      01936   TS      E       BAR.IU.BHZ.93.203               HAR000                          BW      1993,203,06:28:30       1993,203,07:08:29  


pod v 4.x

	New directory structure for pod. Adding in support for location
	codes meant changing station/channel file/directory naming
	conventions.


	Here is the old version of the stn/chn directory:	

                             HAR000
                        -------------------------
        ANMO.II  BAR.G   PFO.II CCM.IU   COL.IU   PFO.TS DGR.IU   H.A  ISA.TS
           |                                         |
    ----------------                        -------------------
   B050  BHE  BHN  BHZ                      B050  BHE  BHN  BHZ


	Here is the new version:

                             HAR000
                        -------------------------
        ANMO.II  BAR.G   PFO.II CCM.IU   COL.IU   PFO.TS DGR.IU   H.A  ISA.TS
           |                                         |
    ----------------                        ------------------------
   B050  BHE.01  BHN.                       B050  BHE.  BHN.01  BHZ.02

Notice the new name for the channel directories. The location code is
tagged onto the channel directory name. In the case of spaces for location
codes, just the dot "." is used. No trailing blanks.




	There is also a new request file structure. All of the fields which
	were no longer used are taken out.

	New request file example:

	
AAK	KN	BHE	  	1993,278,00:00:00	1993,278,23:51:59	AAK.KN.BHE.93.278	HAR000	1993,278,02:01:28	1993,278,02:11:44
AAK	KN	BHN		1993,278,00:00:00	1993,279,00:00:00	AAK.KN.BHN.93.278	HAR000	1993,278,02:01:28     	1993,278,02:11:44 
AAK	KN	BHZ	  	1993,278,00:00:00	1993,279,00:00:00	AAK.KN.BHZ.93.278	HAR000	1993,278,02:01:28	1993,278,02:11:44


	The fields are variable tabbed delimited. 

	Fields names:
	Stn\tNet\tCHN\tLoc\tFile start time\tFile end time\tfile name\t
		stn/chn	directory\trequest start\t request end\n

	New functionality:

	you no longer have to specify pod waveform directories at the 
	station detail. Yuo can specify a umbrella data files directory
	which pod will scan recursively for the files it needs.

	This change was need to as more and more stations were added, 
	pod was running out of environment space.

	Previously you invoked pod with the environment specifiying
	station waveform directories:

	setenv DATA_PATH /data_files/SAA:/data_files/SBB/data_file/ETC

	now:

	setenv DATA_PATH /data_files


	New environment variable:

		PODJUSTDOIT 

	set this to anything and pod will ignore the request file and
	make a seed volume out of any and all files located in its 
	HEADER_PATH and DATA_PATH env variables.

	you still need to specify a dummy request file in the pod 
	command line for a place holder.

	ie:
		setenv PODJUSTDOIT 
		pod seed.me xxxxx 4096 32768 10,100 10,100
