neqn - format equations for character-cell terminal output
neqn [eqn-argument ...]
neqn invokes the eqn(1) command with the ascii output device.
GNU eqn does not support low-resolution, typewriter-like devices, although it may work adequately for very simple input.
Normally, the
path separator in environment variables ending with
PATH is the colon; this may vary depending on the
operating system. For example, Windows uses a semicolon
instead.
GROFF_BIN_PATH
Locate groff commands in these directories, followed by those in PATH. If not set, the installation directory of GNU roff executables, /usr/local/bin, is searched before PATH.
