"""Quick tool to help setup the needed paths and flags
in your Setup file. This will call the appropriate sub-config
scripts automatically.
each platform config file only needs a "main" routine
that returns a list of instances. the instances must
contain the following variables.
name: name of the dependency, as references in Setup (SDL, FONT, etc)
inc_dir: path to include
lib_dir: library directory
lib: name of library to be linked to
found: true if the dep is available
