// This defines protocol for a simple server that lists files.
//
// If you come from high-level programming background, the hardcoded
// maximum lengths may disgust you. However, if your microcontroller only
// has a few kB of ram to begin with, setting reasonable limits for
// filenames is ok.
//
// On the other hand, using the callback interface, it is not necessary
// to set a limit on the number of files in the response.
