Program Listing for File messages.h

// This should probably be functions (with a static variable for the count)
// rather than a class, or else it has to be a singleton because we want
// one global count.

// potentially killing the program if there are too many, and also
// localize decisions like where the error reports go (stdout, stderr, etc)
