The data in the report includes necessary information for starting the compiler service and setting up the project paths in the IDE. the default verbosity of 1 is now set in the compiler code to fix an issue with verbosity being temporary set to 1 during config parsing even when it's explicitly overridden on the command-line. compiler/lexbase was temporary renamed to nimlexbase as a work-around for a codegen naming conflict with lib/pure/lexbase resulting in linking errors (further investigation needed).
