In a recent email the syntax:

It's called "Here string" or "here document" and used extensively in
Bash / Perl / Python / Ruby programming. With 'here doc' You can
disguise entire websites in a single perl file .... or a troff document
http://en.wikipedia.org/wiki/Here_document
I've used Unix/Linux for over 25 years, and I've never seen
that "triple redirect" before. What does it do? I get nowhere
with a Google search because it ignores the '<<<'.
Thanks,
