That syntax is typical of other 'shells'. You'll find it used in csh, ksh, etc. scripts.
It's known as a 'HEREIS' document.
Typically you can feed input to just about any unix command from a file:
I use this syntax all the time:
mailx -s 'the subject' tosomeone@somewhere < message_text_file.txt
When you want to include stuff in-line, in a script, you use a 'hereis' document. You'll
usually find something like this:
mailx -s 'thesubject' tosomeone@somewhere <<<EOF
There is a problem with script X, please contact support
EOF
The '<<<' basically means take the input from stdin (currently the script itself) until you
run into the string "EOF" as the only thing on the input line. There are arguments both for
and against using this feature. I don't particularly care for it.
