That beta for AMD64 linux - take it from
here. Read carefully the readme.txt included there and also podbot.cfg. Settings are cvars now and "addbot" command has been replaced by "add" command (but the syntax is the same). All commands needs to be used with "pb" prefix (regardless if in podbot.cfg or if in console).
pb add 100
pb wpmenu

You need to use these cfgs included into that zip file.
