   <literal>print</literal> is not actually a real function (it is a
   language construct) so you are not required to use parentheses
   with its argument list.

  <para>
   The major differences to <literal>echo</literal> are that
   <literal>print</literal> only accepts a single argument and always returns 1.

This uses the "here document" syntax to output
multiple lines with $variable interpolation. Note
that the here document terminator must appear on a
line with just a semicolon no extra whitespace!
