+.SH NAME
+texeqn \- extracts displayed equations in TeX and LaTeX documents.
+.SH SYNOPSIS
+.B texeqn [-iw]
+.I filename
+.SH DESCRIPTION
+It is sometimes desirable to check only the equations of a document.
+.I Texeqn
+strips those patterns that constitute displayed equations, i.e. anything
+surrounded by
+.I two
+dollar signs, \\begin{equation} and \\end{equation},
+\\begin{eqnarray} and \\end{eqnarray}, or \\begin{displaymath} and
+\\end{displaymath}.
+Note that this also includes any text that is displayed
+in this fashion even if it is not an equation.
+.br
+Macros defines by \\def or \\newcommand are also stripped, since
+the user is likely to use them in those equations.
+Also, \\input and \\include files are inserted unless the
+.B -i
+flag is used.
+.br
+Warning is given if suspected unmatching is detected. Use the
+.B -w
+flag to suppress these warnings.
+.br
+Text commented by '%' is ignored.
+.br
+Using
+.I texeqn
+alone does not typest the equations. If you want them typeset use the
+.B \-eqn
+option with TEX(1).
+.SH DIAGNOSTICS
+Displayed equations that are started and ended by user-defined
+control sequences are nor recognized.
+.br
+White spaces within LaTeX's \\begin{...} and \\end{...} are not allowed for.
