On Linux which has a case-sensitive file system, the classpath in run.bat should refer to 'out/production/Ab' rather than 'out/production/ab'.

I have attached a simple run.sh script (tested on Ubuntu 12.04, but should work on any *nix system with a compatible java command) containing a fix.

I changed the way the classpath and jar files work. Now all the needed jar files are packaged inside one big Ab.jar file, so all you need is

java -cp lib/Ab.jar Main bot=super action=chat trace=false

in your run.bat or run.sh
