 /**
 58   
  * Implementation of FileNameMapper that does simple wildcard pattern
 59   
  * replacements.
 60   
  *
 61   
  * <p>This does simple translations like *.foo -> *.bar where the
 62   
  * prefix to .foo will be left unchanged. It only handles a single *
 63   
  * character, use regular expressions for more complicated
 64   
  * situations.</p>
 65   
  *
 66   
  * <p>This is one of the more useful Mappers, it is used by javac for
 67   
  * example.</p>
