You can set the file to read as the config file via the command line, like this, assuming the program supports it: prog -config=file.cfg You can also override indevidual key-value pairs in the config system using this syntax: prog -Ckey=value Both commands can be used together, and you can override multiple key-value pairs at once. To use this feature of the ConfigUtility, it must receive argc and argv as parameters to the Load() method.
