I made a little shell script to use the gcw0 uncompression tools (unrar, unzip, tar and 7zr) without the command line. It may be of use if you need to uncompress a rom file on the go for example.
It currently can handle .zip, .tar, .tar.gz, .tar.bz2, .rar and .7z files.
The icon is from the Oxygen icon set from KDE. I have included the LGPL license in the opk.
Feel free to modify the script further if you wish.
