[Benchmarking] First pair of load scripts and some considerations

[Shanmugam Ganeshkumar]

Andrea,
I dont have any experince with python, well when I execute the script in
windows OS, this is what I get. installed, python 3.1.1.

C:\Python31>wms_request.py -count 2000 -region -180 -90 180 90 -minres
0.0042 -maxres 0.5 > bluemarble.csv
  File "C:\Python31\wms_request.py", line 37
    print 'Usage: wms_request.py [-count n] [-region minx miny maxx maxy]'
                                                                         ^
SyntaxError: invalid syntax

C:\Python31>python wms_request.py -count 2000 -region -180 -90 180 90
-minres 0.0042 -maxres 0.5 > bluemarble.csv
  File "wms_request.py", line 37
    print 'Usage: wms_request.py [-count n] [-region minx miny maxx maxy]'
                                                                         ^
SyntaxError: invalid syntax



let me know if you can help, else just ignore. Not that important.

Thanks
ganesh
