After a match, these variables contain whatever matched between parentheses
in your regex. If your regex is:

/blah (yada yada) blah/

the $1 variable will contain the string "yada yada" after a successful match.

If your regex contains more than one pair of parentheses:

/blah (yada) yada (blah)/

The $1 variable will contain "yada" and $2 will contain "blah".
