Detecting "default browser"?

[Xavier Roche <roche@httrack.com>]

Hi,

Is there a clean way to detect the default (installed) browser on Debian?
The idea would be to avoid if possible scripts like:

for i in mozilla galeon konqueror ..; do 
  if test -x "/usr/bin/$i"; then 
    /usr/bin/$i $@
    exit $?
  fi
done
