-    <p>To make these functions easier to use, in combination with the
-      function <c>io:get_line</c> which terminates the input line with
-      a new line, the <c>$</c> characters also matches a string ending
-      with <c>"...\n"</c>. The following examples
-      define Erlang data types:</p>
-    <pre>
-Atoms     [a-z][0-9a-zA-Z_]*
-
-Variables [A-Z_][0-9a-zA-Z_]*
-
-Floats    (\+|-)?[0-9]+\.[0-9]+((E|e)(\+|-)?[0-9]+)?</pre>
-    <p>Regular expressions are written as Erlang strings when used with the functions in this module. This means that any <c>\</c> or <c>"</c> characters in a regular expression
-      string must be written with <c>\</c> as they are also escape characters for the string. For example, the regular expression string for Erlang floats is:
-      <c>"(\\+|-)?[0-9]+\\.[0-9]+((E|e)(\\+|-)?[0-9]+)?"</c>.</p>
-    <p>It is not really necessary to have the escape sequences as part of the regular expression syntax as they can always be generated directly in the string. They are included for completeness and can they can also be useful when generating regular expressions, or when they are entered other than with Erlang strings.</p>
