Crapser expands word patterns sent to it by reading the index of words in the database stored in words.R or words.R.wom and returing a new-line delimited list of all terms that match the pattern submitted to it. Additionally, it takes capital letters and expands them to match accented versions of that letter (so E will match </tt>é ê ë è</tt> etc).
