This script will make an index of all the netcdf files in a directory
(including those in subdirectories). It requires Perl 5 and the Perl
NetCDF module. This index has one line per nc file, containing several
fields separated by tabs:

1.  CD name
2.  Path to the NetCDF file, relative to the base directory
3.  Compressed file name (when present)
4.  File name
5.  Minimum woce_date
6.  Maximum woce_date
7.  Minimum latitude in the file
8.  Maximum latitude in the file
9.  Westmost longitude in the file
10. Eastmost longitude in the file
11.  Minimum depth
12.  Maximum depth 
	* Note: mkinv is coded to set min/max depth to 0.0. If you want to determine a 
		range, the code will need to be modified.
13. Experiment ID (expocode)
14. Minimum sea temperature
15. Maximum sea temperature
16. Minimum wind speed
17. Maximum wind speed
18. Platform type and name
19. Existence of heading PL_HD
20. Existence of course PL_CRS
21. Existence of platform speed PL_SPD
22. Existence of platform relative wind direction PL_WDIR
23. Existence of platform relative wind speed PL_WSPD
24. Existence of earth relative wind direction DIR
25. Existence of atmospheric pressure P
26. Existence of air temperature T
27. Existence of wet-bulb temperature TW
28. Existence of dewpoint temperature TD
29. Existence of relative humidity RH
30. Existence of specific humidity Q
31. Existence of precipitation PRECIP
32. Existence of rain rate RRATE
33. Existence of atmospheric radiation RAD
34. Existence of weather code WX
35. Existence of total cloud amount TCA
36. Existence of low/middle cloud amount LMCA
37. Existence of cloud base height ZCL
38. Existence of low cloud type LCT
39. Existence of middle cloud type MCT
40. Existence of high cloud type HCT

Usage:

First, (optionally) edit the variables at the top of mkinv to match
your system. Then, you can just run mkinv with the options listed below,
and it will generate the index for you. 

Here are a few switches you can use:

-o <indexfile>	- sets the output file (this is a REQUIRED field)
-v					- makes mkinv verbose
-h					- prints some simple help
