17.8 The airport-library.dylan file
The airport library implements the main scheduling system for the airport example. This library assumes that your Dylan implementation provides a format-out library, which supplies the format-out and format-to-string functions. This library also assumes that there is a transcendentals library, which supplies the sqrt (square root) function.
