quoting text inside emacs

[Miguel Frasson]

Hi

I often see here quotation of text, specially from hepl of commands
in the format below (with rules drawed with chars)

,---- From The Init File, `~/.emacs' Info Node
| Your site may also have a "site startup file"; this is named
| `site-start.el', if it exists.  Like `default.el', Emacs finds this
| file via the standard search path for Lisp libraries.  Emacs loads this
| library before it loads your init file.  To inhibit loading of this
| library, use the option `-no-site-file'.  *Note Initial Options::.
`----

Which function does it?
