You can do
cvs diff -u DateSelector.java
Which will diff your working version with the one in CVS. The output of
that is what we need.

> * DateSelector is a utility class to handle the creation of a set of
> * date popup menus. The code is broken into a set of static methods
> * for quick and easy access to the individual select objects:
> *
> * <pre>
> * ElementContainer ec dateSelect = new ElementContainer();
> * String myName = "mydate";
> * ec.addElement(DateSelector.getMonthSelector(myName));
> * ec.addElement(DateSelector.getDaySelector(myName));
> * ec.addElement(DateSelector.getYearSelector(myName));
> * </pre>
> *
> * There are also methods which will use attributes to build a
> * complete month,day,year selector:
> *
> * <pre>
> * DateSelector ds = new DateSelector(myName);
> * dateSelect = ds.ecsOutput();
> * </pre>
> *
> * The above element container would use the onChange setting and may
> * hide the selected day if set via showDays().<br>
