 Description:
    Edison is a library of purely functional data structures written by
    Chris Okasaki.  It is named after Thomas Alva Edison and for the
-   mnemonic value EDiSon (Efficent Data Structures).
+   mnemonic value EDiSon (Efficient Data Structures).
    Edison provides several families of abstractions, each with
    multiple implementations.  The main abstractions provided by Edison are:
    Sequences such as stacks, queues, and dequeues;
