[Camino] Getting camino's current version number

I want to write an Applescript that asks Camino, or _uses_ a camino
variable/term to tell me the current version number. I got the idea from
looking in examples with the Apple script editor where the first line was

[  using terms from application "Mail"  ]

thus, I decided if Apple-Script knew how to ask Mail, it might be able
to ask Camino _IF_ I knew the variable name for the current version ...

and, form there, I want to stick it into my signature line in
Thunderbird .... since I update to the nightly and obviously I'd have to
change my sig-line daily ... I am lazy or I forget ... hence some minor
automation ...

So, great implementors, is there such a variable and can it be gleaned
from Apple-Script ?
