There are two ways to configure the client. First, you can use the client's
question/answer configuration. The reconfigure.sh script, located in the
foldingathome directory, is the proper way to do this. Using it ensures that
everything will be updated correctly.
The other route to configuration is by giving options to the client when
starting it. The init script will get these options from two sources. The
first is /etc/default/foldingathome. This is for system-wide options. All
clients will look for it, even those installed to a user's $HOME directory. The
other place is in the configuration directory, foldingathome/config. In here
there should be an option file for each client. These per-client options will
override the system-wide options.
