Hi,
I have a small question about the "convert" command return code.

In GNUpod (http://www.gnu.org/software/gnupod/) the "convert -version" 
command is used to determine (with configure) whether ImageMagick is 
installed.

In the debian ImageMagick 6.3.7 the return code was 0
$ convert -version ; echo $?
Version: ImageMagick 6.3.7 12/10/08 Q16 http://www.imagemagick.org

0

In the ubuntu 6.4.5 version however the return code is 1
$ convert -version ; echo $?

"configure" concludes that ImageMagick is not installed because of the 
return code.

Can you tell me please whether this is a bug?
Maybe there is a better way to determine whether ImageMagick is installed?

Thanks a lot
