Thanks! I'm glad user-setup is being useful.

About the multiple, conflicting instructions: it may not be up-to-date, but 
there is a tweak in the opam files to make them not display the instructions 
when they detect user-setup has been installed as well.

For example, ocp-index has:

    post-messages: "...instructions..." {success & !user-setup:installed}

I think it was put in merlin's definition as well, but didn't get upstream and 
was lost in the updates.

To complete this, the helper packages should mention in their doc "either 
install opam-user-setup, or follow these manual instructions". If they find 
any limitations in user-setup, I invite the maintainers of these packages to 

Put together, these two should be enough to ease the confusion ?

Thanks for the feedback!

PS: another option that was mentionned in the past was to provide a "starter-
kit" metapackage that would install all these tools with a simpler command.
