 Package: rkward
 Type: Package
 Title: Provides functions related to the RKWard GUI
 Description: This package contains functions which are useful in
         combination with the RKWard GUI. Many of these functions only
         needed for the internal communication between RKWard and R, but
         some are also useful in user scripts.
