In normal operation, opam only alters files within ~/.opam.
However, to best integrate with your system, some environment variables
should be set. If you allow it to, this initialisation step will update
your bash configuration by adding the following line to ~/.profile:
Otherwise, every time you want to access your opam installation, you will
need to run:
eval $(opam env)
You can always re-run this setup with 'opam init' later.
Do you want opam to modify ~/.profile? [N/y/f]
(default is 'no', use 'f' to choose a different file) y
A hook can be added to opam's init scripts to ensure that the shell remains in
sync with the opam environment when they are loaded. Set that up? [y/N] y
User configuration:
~/.profile is already up-to-date.
[NOTE] Make sure that ~/.profile is well sourced in your ~/.bashrc.
