// This file gathers configuration parameters related to the user-detectable
// keyboard experience. For example, put key debounce times, repeat rates,
// buffer sized, baud rates, etc. here. Details such as processor clock speed,
// etc. should go in the architecture-dependent files. System details such as
// number of buffer handles, etc. should go with the appropriate module, but
// certain buffer sized may go here if they can affect the user experience (such
// as how long a macro can be).
