Generating checkin differences between two tags on same branch

[Godavarthi, Manasa]

Hi,

I have a script to generate the list of checkins that went between two tags in 
CVS.

The problem I am facing is that when the file gets changed/added for the first 
time on the branch, entries generated by CVS for such file (a dead 1.1
entry) are not shown.

That generates wrong checkin report which I have to manually correct later 
using 'cvs log'.
Sometimes this causes a lot of pain to edit the reports manually.

Is there a better way for doing this?
Or is there a way to tell CVS to show the dead 1.1 entries also?

Thanks in advance,
Manasa
