RAR v3 cannot be extracted by unrar-free on Debian

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Use Debian with only free packages
2. Try using unrar-free package
3. Extracting RARv3 can only be extracted by unrar non-free package.

What is the expected output? What do you see instead?
The files properly being extracted

What version of the product are you using? On what operating system?
Uname: Linux 3.10-2-amd64 Debian 3.10.7-1 (2013-08-17) x86_64 GNU/Linux
Unrar-free version: unrar 0.0.1

Please provide any additional information below.
Peazip has a good discussion about this. Apparently, the unar utility can be 
used on Debian, but unar is written in Objective-C, and RARv3 is a proprietary 
format and should be avoided anyway. Consider using 7-Zip's format (.7z) and 
.tar.gz for source files.
