README addition
Read and write functions; some useful macros
Save two bytes by moving code and changing a JSR to BSR; Correctly display revision number on signon
fkremove() & some macros
Adjustments in test; noticing fksprintf() won't work for strings > 480 bytes
Some bugs ironed out, mainly I hadn't counted on vsnprintf() trashing the arg list. Also, library order in makefile.
Font tweaks
Polish symbols, save some cycles
