A.1.2 Unix Configuration Files

When AVRDUDE is build using the default `--prefix' configure option, the default configuration file for a Unix system is located at /usr/local/etc/avrdude.conf. This can be overridden by using the `-C' command line option. Additionally, the user's home directory is searched for a file named .avrduderc, and if found, is used to augment the system default configuration file.
