Linux "geqn" Command Line Options and Examples
format equations for troff or MathML
This manual page describes the GNU version of eqn, which is part of the groff document formatting system. eqn compiles descriptions of equations embedded within troff input files into commands that are understood by troff. Normally, it should be invoked using the -e option of groff.
Usage:
eqn [-rvCNR] [-d xy] [-T name] [-M dir] [-f F] [-s n] [-p n] [-m n] [files...]
Command Line Options:
-N
Don't allow newlines within delimiters. This option allows eqn to recover better from missing closing delimiters.

-v

geqn -v ...
-r
Only one size reduction.
geqn -r ...

geqn -Mdir ...
-R
