What i have done is found in synaptiuc. I installed nautilus-gksu and
nautilusscript-manager. Then I installed ubuntu tweak from www.getdeb. There is
asection in it for setting up scripts. Works good for me. I have one script in
right click menue that dose open file as adm.and one sub menue that is scripts
with 7 more scrips in it. I use it in 8.04 and 8.10.
