This manual page describes the GNU version of eeeeqqqqnnnn, which is
part of the groff document formatting system. eeeeqqqqnnnn compiles
descriptions of equations embedded within ttttrrrrooooffffffff input files
into commands that are understood by ttttrrrrooooffffffff. Normally, it
should be invoked using the ----eeee option of ggggrrrrooooffffffff. The syntax
is quite compatible with Unix eqn. The output of GNU eqn
cannot be processed with Unix troff; it must be processed
with GNU troff. If no files are given on the command line,
the standard input will be read. A filename of ---- will cause
the standard input to be read.
eeeeqqqqnnnn searches for the file eeeeqqqqnnnnrrrrcccc using the path
....::::////uuuussssrrrr////llllooooccccaaaallll////lllliiiibbbb////ggggrrrrooooffffffff////ttttmmmmaaaacccc::::////uuuussssrrrr////lllliiiibbbb////ttttmmmmaaaacccc. If it exists,
eqn will process it before the other input files. The ----RRRR
option prevents this.
GNU eqn does not provide the functionality of neqn: it does
not support low-resolution, typewriter-like devices
(although it may work adequately for very simple input).
OOOOPPPPTTTTIIIIOOOONNNNSSSS
----CCCC Recognize ....EEEEQQQQ and ....EEEENNNN even when followed by a character
other than space or newline.
----NNNN Don't allow newlines within delimiters. This option
allows eeeeqqqqnnnn to recover better from missing closing
delimiters.
----vvvv Print the version number.
----rrrr Only one size reduction.
----mmmm_n The minimum point-size is _n. eqn will not reduce the
size of subscripts or superscripts to a smaller size
than _n.
----TTTT_n_a_m_e
The output is for device _n_a_m_e. The only effect of this
is to define a macro _n_a_m_e with a value of 1111. Typically
eeeeqqqqnnnnrrrrcccc will use this to provide definitions appropriate
for the output device. The default output device is
