[ale] Utility to word-wrap plain text?

Good morning,

I have users of a web site submitting text in a <textarea> tag.  The form is
later delivered to via email.

The problem I'm encountering is that while the user types in the textarea, words
are automatically wrapped within the space provided.  However, when I receive
the contents of the tag, no word wrapping occurs unless the user specifically
included a newline.

Does anyone have any ideas on how I can take the contents of a bash shell
variable and word-wrap it to, oh say, 72 columns?

Thanks,
    - Chuck
