    //
    //This class used to be called JcsFileFilter. I renamed it to JCSFileFilter
    //and the Unix developers reported they were getting errors. So I deleted
    //the file from the CVS repository and tried to re-add it, but I got
    //CVS errors:
    //
    //  cvs server: cannot add file `com/vividsolutions/jcs/workbench/ui/JCSFileFilter.java'
    //  when RCS file `/home/cvs/jcs/jcs/com/vividsolutions/jcs/workbench/ui/JCSFileFilter.java,v'
    //  already exists
    //  cvs [server aborted]: correct above errors first!
    //
    //This is a CVS bug mentioned on the Usenet newsgroups (deleting and re-adding
    //a file). So I just renamed it to something totally different:
    //WorkbenchFileFilter. [Jon Aquino]
