Package texlive-match_parens

http://tug.org/texlive/

Mismatches of parentheses, braces, (angle) brackets, especially in TeX sources
which may be rich in those, may be difficult to trace. This little Ruby script
helps you by writing your text to standard output, after adding a left margin
to your text, which will normally be almost empty, but will clearly show any
mismatches.
