# Report or get rid of duplicates in various components of a dictionary.
# Usage:
#	zapdups [-d [-n]] [-l langfile] dict-0 dict-1 ...
# Dictionaries starting with dict-1 (not dict-0!) are examined,
# looking for words that appear in any earlier dictionary.  If any
# duplicates are found, they are reported to the standard output.
# If the -d switch is specified, duplicates are removed from later
# dictionaries.  The modification is done in-place.  This switch
# should normally be used after examining the output of an earlier
# run.  The -d switch takes a long time to run, because it uses
# munchlist to reduce the dictionary once duplicates are removed.
# The -n switch can be used to suppress the running of munchlist, to
# save time.
# If the -l switch is specified, the language tables are gotten from
# the specified file; otherwise they come from $LIBDIR/!!DEFLANG!!.
