Description

It is not currently posible to determine if an entry in a tar archive denotes a symbolic link or not; the only existing query mechanism is: isDirectory()

I propose to add the following patch to:
commons-compress-1.1-src/src/main/java/org/apache/commons/compress/archivers/tar/TarArchiveEntry.java

Thanks much in advance,
