Add a Customize_utils module. This contains common error/warning/info functions, and also quote = Filename.quote. Examine every existing call to printf/eprintf and change where necessary so that: - error is used instead of eprintf + exit 1 - warning no longer needs ~prog argument (it is added by Utils module) - any verbose output should go to stdout, not stderr - info is used to print general informational messages Also, don't pass ~prog parameter around. Instead we just get it from the executable name.
