org.apache.commons.compress.archivers.cpio.CpioArchiveInputStream
CPIOArchiveInputStream is a stream for reading cpio streams. All formats of cpio are supported (old ascii, old binary, new portable format and the new portable format with crc).

The stream can be read by extracting a cpio entry (containing all informations about a entry) and afterwards reading from the stream the file specified by the entry.
```
 CPIOArchiveInputStream cpioIn = new CPIOArchiveInputStream( new FileInputStream(new File("test.cpio"))); CPIOArchiveEntry cpioEntry;  while ((cpioEntry = cpioIn.getNextEntry()) != null) { System.out.println(cpioEntry.getName()); int tmp; StringBuilder buf = new StringBuilder(); while ((tmp = cpIn.read()) != -1) { buf.append((char) tmp); } System.out.println(buf.toString()); } cpioIn.close(); 
```
Note: This implementation should be compatible to cpio 2.5 This class uses mutable fields and is not considered to be threadsafe. Based on code from the jRPM project (jrpm.sourceforge.net)
