Description

IndexFileNames is useful for applications that extend Lucene, an in particular those who extend Directory or IndexWriter. It provides useful constants and methods to query whether a certain file is a core Lucene file or not. In addition, IndexFileNames should be used by Lucene's code to generate segment file names, or query whether a certain file matches a certain extension.

I'll post the patch shortly.
