[Za-pm] perl Command line switch

[Spike]

Hi All
It's very quiet out there - guess we must all be too good to have problems :-)

Is there a -w type of flag that will list all the variables I have declared 
with 'my' but have not used?
I have some horribly messy scripts that have been growing over the last 
year and need a good clean out!
... for that matter is there and easy way to list sub-routines that don't 
get used? (probably not)
