[rt-users] How to check the version of an installed RTFM ?

[Gerard FENELON]

Hello

I am considering upgrading our version of RTFM.
However actions described in the UPGRADE depend on the version of the 
installed RTFM
and we seem to have lost that information.
I only know that it was installed in 2004.
It does not seem to be on the pages like the version of RT.
I don't see an obvious file and I don't see anywhere in the database.

Does any one know of a way of getting that information ?

Thanks
Gerard
