Installing ASC for Linux
You can either compile ASC yourself or get a prebuild ASC package for your Linux distribution.
Compiling ASC should be quite hassle free, once you have all required libraries installed. All up-to-date Linux distribution should provide the required libs. You can download the source code from SourceForge
Many Linux distribution already provide ASC, either directly or through their community package repositories. But these versions are not necessarily up to date.
You can also check if there are third-party RPM for your distribution, for example at http://rpm.pbone.net/
