Description
WELCOME
In computing, a regular expression, also referred to as "regex" or "regexp", provides a concise and flexible means for matching strings of text, such as particular characters, words, or patterns of characters. A regular expression is written in a formal language that can be interpreted by a regular expression processor.

WHY REGEX?
Really clever "wild card" expressions for matching and parsing strings.
Very powerful but quite cryptic
Fun once you understand them
A language of "marker characters" - programming with characters
It is kind of an "old school" language - compact
