It is in the "module contents" section. You need to specify a flag as
an optional argument. You can have not only "word wraps" and comments
but also whitespace between conceptual "words".
This flag allows you to write regular expressions that look nicer.
Whitespace within the pattern is ignored, except when in a character
class or preceded by an unescaped backslash, and, when a line contains
a "#" neither in a character class or preceded by an unescaped
backslash, all characters from the leftmost such "#" through the end
of the line are ignored.
If you are having trouble parsing the second sentence, try
substituting "nor" instead of the second "or".
