From the sound of it your merge relates to merged webhelp
sitting on a server rather than merged CHMs sitting locally. If so,
then there is a full article on my site explaining the procedure.
Whilst the screens are from earlier versions of RH, the procedure
is still unchanged in RH7.
Essentially you will create a parent project which is just a
shell. Then you create child projects as required. Any one customer
gets the parent and just those child projects they require. For
that reason you will need to be careful about creating cross
project links so that you do not link to a topic that the client
might not have. 404 errors are not pretty!
