How to get changelog between two tags

[alederer]

Hello,

I know there are some discussions in the past about using tags with cvs log,
but I found no answer to my current problem.

I need to get the changes which are made on some files since a specific tag.
My Problem is to get also changes from files, which don't have the specified
tag, because they are added to cvs after the tag has been generated.

What I have tried, is to use the following syntax:
cvs log -rTag1::Tag2 

Is it possible to get the changes for files which don't have Tag1 but have
Tag2 ?

It is not possible to use the file revision (e.g. 1.13), because I have many
files (~28000) and it would take to long to get the possible filerevisions
for cvs log -rFileRev::Tag2 .

Is there a other way, or a hidden parameter, to get also files which don't
have the Tag "Tag1"?

Thanks
Andreas
