- `rbbp` packages gem files into *vendor/cache*.

Functions
---------
- `ruby-info` exposes information about the Ruby environment via the
`$ruby_info` associative array.
Theming
-------
To display the name of the current Ruby version in a prompt, define the
following style in the `prompt_theme_setup` function.
# %v - ruby version.
zstyle ':prezto:module:ruby' version 'version:%v'
Then add `$ruby_info[version]` to `$PROMPT` or `$RPROMPT` and call
`ruby-info` in the `prompt_theme_preexec` hook function.
