I am not Chris, but I can answer your question. 'qq' is a quote-operator
that interprets its argument in a double-quote context, interpolating the
values of variables and escape sequences and returning a scalar value. Thus,
qq($a, $b\n) is equivalent to "$a, $b\n".
qq() is often used to improve readability. One advantage is that embedded
double-quote characters do not need to be escaped. For example, qq(") is
equivalent to "\"", but more readable.
See 'perldoc perlop' and search for 'Quote and Quote-like Operators'.
