org.apache.commons.compress.archivers.ArchiveInputStream
Archive input streams MUST override the {@link #read(byte[],int,int)} - or {@link #read()} -method so that reading from the stream generates EOF for the end of data in each entry as well as at the end of the file proper.
The {@link #getNextEntry()} method is used to reset the input streamready for reading the data from the next entry.
The input stream classes must also implement a method with the signature:
```
 public static boolean matches(byte[] signature, int length) 
```
which is used by the {@link ArchiveStreamFactory} to autodetectthe archive type from the first few bytes of a stream.
