  "Description": "Implements a simple key-value style database where\ncharacter string keys are associated with data values that are\nstored on the disk. A simple interface is provided for\ninserting, retrieving, and deleting data from the database.\nUtilities are provided that allow 'filehash' databases to be\ntreated much like environments and lists are already used in R.\nThese utilities are provided to encourage interactive and\nexploratory analysis on large datasets. Three different file\nformats for representing the database are currently available\nand new formats can easily be incorporated by third parties for\nuse in the 'filehash' framework.",
