[Orgmode] OFF-TOPIC - posting file snippets..

[sergio_101]

i realize that this is off topic, but i think it will help in the future
as i continue to post..

i have seen lots of people posting file snippets to this list that are
really well formatted.. something like:

--[filename.txt]--
| contents of |
|file         |
---[end]---

well, not that ugly, but you get the idea..

my question is.. how are they doing that?

thanks!
