Keypad library error

Every time I compile my program I get this error message:

fatal error: keypad.h: no such file or directory.

Every time I compile my program I get this error message:

fatal error: keypad.h: no such file or directory.

Well, I suggest that you try compiling a couple hundred more times, in the forlorn hope that the Keypad library will magically download itself and properly install itself.
