/**
 * This is the PrintfC component.  It provides the printf service for printing
 * data over the serial interface using the standard c-style printf command.  
 * Data printed using printf are buffered and only sent over the serial line after
 * the buffer is half full or an explicit call to printfflush() is made.  This 
 * buffer has a maximum size of 250 bytes at present.  This component is wired
 * to a shadowed MainC component so that printf statements can be made anywhere 
 * throughout your code, so long as you include the "printf.h" header file in 
 * every file you wish to use it.  Take a look at the printf tutorial (lesson 15)
 * for more details.
 *
 * The printf service is currently only available for msp430 based motes 
 * (i.e. telos, eyes) and atmega128x based motes (i.e. mica2, micaz, iris).  On the
 * atmega platforms, avr-libc version 1.4 or above must be used.
