I dont accept binary blobs on my computer. Everything installed must be full open source (even if I install a package that was compiled by the distro maintainers)

I want to install a good unrar that satisfies this rule, opens rar's well, and i'd prefer it to work with Ark (but dont mind too much)

Wikiedia says : http://en.wikipedia.org/wiki/Rar
unrarlib - free but opens up to rar v2.x
the unarchiver (xad) - free
unrar - blob

My distro now supplies only the blob, but in the past usd to supply unrar-free too

the site of unrar-free says : http://gna.org/projects/unrar/
it's unrarlib

the site of unrarlib says : http://www.unrarlib.org/
it supports up to 2.x
here is the source of unrar (link)

the source of unrar is here ftp://ftp.rarlabs.com/rar/unrarsrc-3.7.8.tar.gz



1 The "blob"'s source looks like source, there are no files that look like binaries inside. So is it open sourced ?

2 Excluding this one, you have other suggestions ?

ftp://ftp.rarlabs.com/rar/unrarsrc-3.7.8.tar.gz : Freeware.
The file 'licence.txt' "All copyrights to RAR and the utility UnRAR are
exclusively owned by the author - Alexander Roshal."

Rarlinux 32bits http://www.rarlab.com/rar/rarlinux-4.0.b3.tar.gz
'licence.txt' "The author and holder of the copyright of RAR and WinRAR
is Alexander L. Roshal."

64bits http://www.rarlab.com/rar/rarlinux-x64-4.0.b3.tar.gz

I think, those are the choices.
