+@command{avr-gcc}.  It uses avr-gcc's own register definition to simplify
+creating new targets for supported AVR devices.  The core was made to be small
+and compact, and hackable so allow quick prototyping of an AVR project.  The
+AVR core is now stable for use with parts with <= 128KB flash, and with
+preliminary support for the bigger parts.  The simulator loads ELF files
+directly, and there is even a way to specify simulation parameterps directly
+in the emulated code using an @code{.elf} section.  You can also load
+multipart HEX files.")
