# TeXinfo

TeXinfo is a TeX dialect designed by GNU. It uses `@` to start a control sequence,
which is different from other TeX dialects. GNU also create some perl programs
to convert texinfo to `info`, `HTML`, ..., while other TeX dialects doesn't have
good support for outputting HTML like [TeX4ht](https://tug.org/tex4ht/) for
PlainTeX/LaTex/ConTeXt.

`main.texi`:

```texinfo
