Version 3.0 finaly released!
TeXcount is a Perl script for counting words in LaTeX documents. It parses valid LaTeX documents counting words, headers, formulae (mathematics) and floats/begin-end groups.
TeXcount is included in the CTAN TeX/LaTeX archive, and thus included in several TeX distributions. If you have TeX installed, chances are you may already have TeXcount.
