X.SH NAME
Xtexmatch \- checks matching in TeX and LaTeX documents.
X.SH SYNOPSIS
X.B texmatch [-i]
X.I filename
X.SH DESCRIPTION
X.I Texmatch
Xgives error messages if it detects unmatched
Xbraces, brackets, parentheses, and equations in TeX and LaTeX documents.
XError messages are sent
Xto the standard error.
X.br
XEscaped braces, brackets, parentheses, and dollar signs are not
Xcounted. It understands TeX's rules of escaping and dollar signs
Xpairing as well as LaTeX's \\begin{equation} and \\end{equation}.
XIt also checks \\input and \\include files unless the
X.B -i
Xflag is used.
X.br
XText and displayed equations are checked separately.
X.br
XCommented text is not checked.
X.SH DIAGNOSTICS
XDisplayed equations that are started and ended by user-defined
Xcontrol sequences are regarded as text and they are not checked
Xseparately.
X.br
XDoes not check for matching \\begin and \\end in LaTeX environments
Xother than equations.

Xtexexpand(1), texeqn(1).

X.SH DESCRIPTION
X.I Trmatch
Xgives error messages if it detects unmatched
Xbraces, brackets, parentheses, equations, and
Xdollar signs in troff documents.
XError messages are sent to the standard error.
X.br
XEscaped braces, brackets, parentheses, and dollar signs are not counted.
XText and equations are checked separately.
XIt takes equations to be delimited by .EQ and .EN.
XIf a ``define'' occurs in the equation, the line containing
Xthe ``define'' is not checked (since it is bound to have unmatches).
X.SH DIAGNOSTICS
XDisplayed equations that are started and ended by user-defined
Xcontrol sequences are regarded as text and matching is not checked
Xseparately.
