Texinfo
A {GNU} documentation system that uses a single source file to
produce both on-line information and printed output. You can
read the on-line information, known as an "{Info} file", with
an Info documentation-reading program. By convention, Texinfo
source file names end with a ".texi" or ".texinfo" extension.
You can write and format Texinfo files into Info files within
{GNU Emacs}, and read them using the Emacs Info reader. If
you do not have Emacs, you can format Texinfo files into Info
files using "{makeinfo}" and read them using "info". {TeX} is
used to typeset Texinfo files for printing.
Texinfo is available from your nearest {GNU archive site}.
