-At its most basic, a regular expression
-is a template that is used to determine if a string has certain
-characteristics. The string is most often some text, such as a line,
-sentence, web page, or even a whole book, but less commonly it could be
-some binary data as well.
-Suppose we want to determine if the text in variable, C<$var> contains
-the sequence of characters S<C<m u s h r o o m>>

-The value of this expression will be TRUE if C<$var> contains that
-sequence of characters, and FALSE otherwise. The portion enclosed in
-C<'E<sol>'> characters denotes the characteristic we are looking for.
-We use the term I<pattern> for it. The process of looking to see if the
-pattern occurs in the string is called I<matching>, and the C<"=~">
-operator along with the C<m//> tell Perl to try to match the pattern
-against the string. Note that the pattern is also a string, but a very
