The 'm' is an optional flag indicating that a 'match' regexp (versus a
substitution or transliteration) follows. It's typically only necessary
in perl if using delimiters other than / around the regexp.
(The person who posted that should have written it as PHP to avoid
confusion: preg_match('/^[0-9][A-Z][a-z]{2-3} \.[0-9]+$/', $string);)
