Load $brew_name automatically in POSIX compatible shells (ash, dash, ksh and
similar) by adding
  eval "\$($brew_exec init Sh)"
to ~/.profile.
This can be easily done using:
  echo 'eval "\$($brew_exec init Sh)"' >> ~/.profile
Note that this enables rakubrew *only* in login shells.
To get rakubrew also working in non-login shells, you need the following:
  echo 'export ENV=~/.shrc' >> ~/.profile
  echo 'eval "\$($brew_exec init Sh)"' >> ~/.shrc
Make sure that `ENV` is not already set to point to some other file.

================================ WARNING ======================================
rakubrews home directory is currently
  $prefix
That folder contains spaces. This will break building rakudos as the build
system currently doesn't work in such a path. You can work around this problem
by changing that folder to a directory without spaces. Do so by putting
  export RAKUBREW_HOME=/some/folder/without/space/rakubrew
in your `~/.profile` file.
