+Lets you specify the naming constraints for different Java source file elements. These
+constraints are naturally expressed with regular expressions (Perl 5.003 syntax).
+
+The list component displays all covered elements along with their current regular
+expression.
+
+Selecting an item in the list and either pressing the Change...
+button or double-clicking on the item will open a little regular expression testing tool
+that can be used to interactively craft a valid regular expression.
+
4.4.2.1. Regular expression tester
+The regular expression tester lets you interactively specifiy a valid regular expression
+that matches a certain String pattern.
+
+Regexp
+
+The Regexp text field is where you have to insert the regular
+expression. This text field initially contains the current regular expression for the
+list item that is under construction.
+
+The used regular expression syntax is that of Perl 5.003. See Mastering Regular
+Expressions [Friedl97] for an in-depth look at this
+regular expression flavor.
+
+String
+
+The String text field is where you have to type a String that should
+be matched by the specified regular expression. This text field is initially empty; you
+have to enter a String in order to be able to test the regular expression.
+
+Once you have setup up the text fields you can either use the Test
+button to soley perform the pattern matching test or the Apply button
+which both performs testing and - on success - closes the dialog and updates the list.
+
+You can always use the Cancel button to cancel editing. The dialog
+will be closed nd no changes made to the list.
