* TODO: Updated. Added point about plustek-share.h using c++ comment
	  and reminder to check config.in.h. Removed entriy about as6e.c stat
	  result check.
	* backend/as6e.c backend/as63.h: Comitted patch from Eugene Weiss
	  <eweiss@sas.upenn.edu>. Fixes: Use only DBG (no printfs). Check result
	  of stat. Add GPL header.
