what about my simple proposal for tde-open

"what about having an alias for "kfmclient exec" to tde-open?
There is kde-open, mate-open, gnome-open... tde-open would be a logical 
expectation."

a simple wrapper script

#!/bin/bash
kfmclient exec "@"

in /opt/trinity/bin
named tde-open

should do the trick.....
