Okay, as a simple commitment to the community I'd like to start a list of software (excluding Compiler's and IDE's) for beginning indie developers, that is either free or available for a relatively low price. Currently it's just a list of few titles that came to my mind, but please post cuggestions to this list, so we can make it as complete as possible!
