If true indicate the regular expression should treat input as having multiple lines. This option affects the interpretation of the ^ and $ metacharacters. When true the ^ metacharacter matches at the beginning of every line, and the $ metacharacter matches at the end of every line. Additionally the . metacharacter will not match newlines when true.
