==> Caveats
readline is keg-only. This means it is not symlinked into Homebrew's
prefix. The formula provides the following rationale:

OS X provides the BSD Readline library. In order to prevent conflicts when
programs look for libreadline we are defaulting this GNU Readline installation
to keg-only.


Generally there are no consequences of this for you, however if you build your
own software and it requires this formula, you may want to run this command to
link it into the Homebrew prefix:

     brew link readline
