[wmeyer48]

Is there a tool which can be used to extract a concordance from the chapters in a LaTeX project? The motivation is to proceed by stages to develop a list of words in a long document which should be indexed. Or perhaps there is some tool already built which can do that? Ideally, it would accept lists of words to exclude.
