Here's a startup script ( /usr/local/bin/oo2) for oo2.tczl  that replaces the user.tar.gz (no longer supported).  I added a flag so files are copied only once, and had the menu and  icon point to it instead of soffice.     
 
#!/bin/sh
if [ ! -e /tmp/oo2-flag ]; then 
 if [ -d /tmp/tcloop/oo2/usr/local/bin/ ]; then 
         sudo cp -Rp /tmp/tcloop/oo2/usr/local/bin/* /usr/local/bin/
         sudo touch /tmp/oo2-flag
 fi    
fi 
/usr/local/bin/soffice 
exit 0
Edit: Looks like scripts run from /usr/local/tce.installed....much simpler.
