This module is a variation on the lovely Text::Diff module. Rather than
generating traditional line-oriented diffs, however, it generates word-oriented
diffs. This can be useful for tracking changes in narrative documents or
documents with very long lines. To diff source code, one is still best off
using Text::Diff. But if you want to see how a short story changed from one
version to the next, this module will do the job very nicely.
