Function for displaying arbitrary text as in 'help'.

Hi all,

I am looking for a function that receives some text (any text) and displays
it to the user in the same way as the 'help' function does. Unlike 'cat',
that outputs the text in the current window, the one I'm looking for should
work as 'help' that, for example, in emacs ess opens a new buffer, in the
linux terminar displays it as the more command, etc. Is there any function
that does this?
