< p > AVRDUDE reads a configuration file upon startup which describes all of
the parts and programmers that it knows about. The advantage of this is
that if you have a chip that is not currently supported by AVRDUDE, you
can add it to the configuration file without waiting for a new release
of AVRDUDE. Likewise, if you have a parallel port programmer that is
not supported by AVRDUDE, chances are good that you can copy and
existing programmer definition, and with only a few changes, make your
programmer work with AVRDUDE.

< p > AVRDUDE first looks for a system wide configuration file in a platform
dependent location. On Unix, this is usually
< code > /usr/local/etc/avrdude.conf< / code > , while on Windows it is usually in the
same location as the executable file. The name of this file can be
changed using the ‘ < samp > -C< / samp > ’ command line option. After the system wide
configuration file is parsed, AVRDUDE looks for a per-user configuration
file to augment or override the system wide defaults. On Unix, the
per-user file is < code > .avrduderc< / code > within the user’ s home directory. On
Windows, this file is the < code > avrdude.rc< / code > file located in the same
directory as the executable.
