[gdal-dev] os.remove and os.unlink in the testsuite

[Ben Elliston]

Hi Even

What do you think about adding some convenience functions to the
gdaltest module like "try_remove" and "try_unlink" that never throw an
exception if the file doesn't exist?  This would remove a lot of lines
like these from the test cases:

try:
  os.unlink('some file')
except OSError:
  pass

Cheers, Ben
