  * A regular expression datatype.  Keeps an instance of the
 65   
  * compiled expression for speed purposes.  This compiled
 66   
  * expression is lazily evaluated (it is compiled the first
 67   
  * time it is needed).  The syntax is the dependent on which
 68   
  * regular expression type you are using.  The system property
 69   
  * "ant.regexp.regexpimpl" will be the classname of the implementation
 70   
  * that will be used.

  *   org.apache.tools.ant.util.regexp.JakartaOroRegexp (the default)

 80   
  * For jdk &gt;= 1.4 an additional implementation is available:
 81   
  *   org.apache.tools.ant.util.regexp.Jdk14RegexpRegexp
 82   
  *        Based on the jdk 1.4 built in regular expression package.
