+It's designed primarily for checking misspelled words in source code,
+but it can be used with other files as well.  It does not check for word
+membership in a complete dictionary, but instead looks for a set of
+common misspellings.  Therefore it should catch errors like \"adn\", but
+it will not catch \"adnasdfasdf\".  This also means it shouldn't
+generate false-positives when you use a niche term it doesn't know
+about.")
