      """Some helpful extensions and modifications to the 'ggplot2'
      package. In particular, this package makes it easy to combine
      multiple 'ggplot2' plots into one and label them with letters,
      e.g. A, B, C, etc., as is often required for scientific
      publications. The package also provides a streamlined and clean
      theme that is used in the Wilke lab, hence the package name,
      which stands for Claus O. Wilke's plot package."""
