## Detailed Description

    Token for matching strings that match a given regular expression.
       Defined with string specifying the regular expression in a form recognized by the inbuilt Python re module.

    The parameters pattern and flags are passed to the re.compile() function as-is. See the Python re module for an explanation of the acceptable patterns and flags.
