/**
 * SpellCorrector.java
 *
 * @author Jeff Ondich
 * @version 5/3/05
 *
 * This main program uses the Dictionary class to create a primitive
 * spelling corrector.  It takes two command line arguments: first,
 * the name a file consisting of one lower-case word per line, in
 * alphabetical order; and second, a file consisting of a list of
 * words to be spell-corrected.  As I said, this is a very primitive
 * spelling corrector--punctuation will throw it off (for example,
 * the word "example" from the previous line would be accompanied by
 * its comma if this comment were the file to be corrected).
 *
 * This program is part of an exercise on profiling, and thus has
 * been left intentionally in a non-optimal state.
