How to print a literal '.' as the first character in a line?

[Alejandro Colomar]

I'd like to be able to print a '.' in a document, and it happens to be 
at the start of a line.  I've read there's a way to change the request 
character from '.' to some other character, but is there any simpler way 
to do that?

Simple (and a bit stupid) example:
[
.EX
$ echo '.'
.
.EE
]

You get the idea, I guess.
Ho do I do that?

Thanks,

Alex
