-
-This library is realy just two files: 'printf.h' and 'printf.c'.
-
-They provide a simple and small (+200 loc) printf functionality to
-be used in embedded systems.
-
-I've found them so usefull in debugging that I do not bother with a
-debugger at all.
-
-They are distributed in source form, so to use them, just compile them
-into your project.
-
-Two printf variants are provided: printf and sprintf.
-
-The formats supported by this implementation are: 'd' 'u' 'c' 's' 'x' 'X'.
-
-Zero padding and field width are also supported.
-
-If the library is compiled with 'PRINTF_SUPPORT_LONG' defined then the
-long specifier is also
-supported. Note that this will pull in some long math routines (pun intended!)
-and thus make your executable noticably longer.
-
-The memory foot print of course depends on the target cpu, compiler and
-compiler options, but a rough guestimate (based on a H8S target) is about
-1.4 kB for code and some twenty 'int's and 'char's, say 60 bytes of stack space.
-Not too bad. Your milage may vary. By hacking the source code you can
-get rid of some hunred bytes, I'm sure, but personally I feel the balance of
-functionality and flexibility versus  code size is close to optimal for
-many embedded systems.
-
-To use the printf you need to supply your own character output function,
-something like :
-
-    void putc ( void* p, char c)
-        {
-        while (!SERIAL_PORT_EMPTY) ;
-        SERIAL_PORT_TX_REGISTER = c;
-        }
-
-Before you can call printf you need to initialize it to use your
-character output function with something like:
-
-    init_printf(NULL,putc);
-
-Notice the 'NULL' in 'init_printf' and the parameter 'void* p' in 'putc',
-the NULL (or any pointer) you pass into the 'init_printf' will eventually be
-passed to your 'putc' routine. This allows you to pass some storage space (or
-anything realy) to the character output function, if necessary.
-This is not often needed but it was implemented like that because it made
-implementing the sprintf function so neat (look at the source code).
-
-The code is re-entrant, except for the 'init_printf' function, so it
-is safe to call it from interupts too, although this may result in mixed output.
-If you rely on re-entrancy, take care that your 'putc' function is re-entrant!
-
-The printf and sprintf functions are actually macros that translate to
-'tfp_printf' and 'tfp_sprintf'. This makes it possible
-to use them along with 'stdio.h' printf's in a single source file.
-You just need to undef the names before you include the 'stdio.h'.
-Note that these are not function like macros, so if you have variables
-or struct members with these names, things will explode in your face.
-Without variadic macros this is the best we can do to wrap these
-fucnction. If it is a problem just give up the macros and use the
-functions directly or rename them.
-
-For further details see source code.

-This file documents changes in the firmware-only USB driver for atmel's AVR
-microcontrollers. New entries are always appended to the end of the file.
-Scroll down to the bottom to see the most recent changes.
-
-2005-04-01:
-  - Implemented endpoint 1 as interrupt-in endpoint.
-  - Moved all configuration options to usbconfig.h which is not part of the
-    driver.
-  - Changed interface for usbVendorSetup().
-  - Fixed compatibility with ATMega8 device.
-  - Various minor optimizations.
-
-2005-04-11:
-  - Changed interface to application: Use usbFunctionSetup(), usbFunctionRead()
-    and usbFunctionWrite() now. Added configuration options to choose which
-    of these functions to compile in.
-  - Assembler module delivers receive data non-inverted now.
-  - Made register and bit names compatible with more AVR devices.
-
-2005-05-03:
-  - Allow address of usbRxBuf on any memory page as long as the buffer does
-    not cross 256 byte pag
