Rarun2 is used as a launcher for running programs with different environment, arguments, permissions, directories and overridden default file descriptors.

The program just accepts a single argument which is the filename of the configuration file to run the program. It is useful when you have to run a program using long arguments or pass long data to stdin or things like that usually required for exploiting crackmes :) RaRun2
