## Plugin options
* Set `SHOW_AWS_PROMPT=false` in your zshrc file if you want to prevent the plugin from modifying your RPROMPT.
Some themes might overwrite the value of RPROMPT instead of appending to it, so they'll need to be fixed to

## Theme
The plugin creates an `aws_prompt_info` function that you can use in your theme, which displays
the current `$AWS_PROFILE`. It uses two variables to control how that is shown:
the current `$AWS_PROFILE` and `$AWS_REGION`. It uses four variables to control how that is shown:
* ZSH_THEME_AWS_PREFIX: sets the prefix of the AWS_PROFILE. Defaults to `<aws:`.
* ZSH_THEME_AWS_PROFILE_PREFIX: sets the prefix of the AWS_PROFILE. Defaults to `<aws:`.
* ZSH_THEME_AWS_SUFFIX: sets the suffix of the AWS_PROFILE. Defaults to `>`.
* ZSH_THEME_AWS_PROFILE_SUFFIX: sets the suffix of the AWS_PROFILE. Defaults to `>`.
* ZSH_THEME_AWS_REGION_PREFIX: sets the prefix of the AWS_REGION. Defaults to `<region:`.
* ZSH_THEME_AWS_REGION_SUFFIX: sets the suffix of the AWS_REGION. Defaults to `>`.
