You didn't. Chris and I just both happen to have coded our own gdal_calc 
script. They are different, each might have its pro's and con's. Sorry 
if I created some confusion... I just thought it might be interesting to 
have both implementations.

Feel free to upload it (can't speak for Chris, of course), and to 
use/modify to your needs. However, putting it in some examples folder 
might be more appropriate?, as I don't intend to do lots of maintenance 
on this script. I just use it, and if I encounter a bug or need more 
functionality, I code it. It is the result of some years of evolution, 
however I personally don't feel the code is 'production quality'...

Regards,
Vincent.
