The server config file is located in ~/.winswitch/server/server.conf on *nix, *\Application Data\Window-Switch\server\server.conf on MS Windows.
It will be generated automatically when you run winswitch_server for the first time.

Sensible default values may be specified for the whole server in the file /etc/winswitch/server_defaults.conf (Unix-like only), which may contain any of the values documented below, except for the unique identifier ID and the encryption keys as those must be unique to each server instance.

Most options should be self explanatory and can be overriden from the command line using "--OPTION_NAME=VALUE"
(or more simply "--OPTION_NAME" or "--no-OPTION_NAME" for boolean types)
For example, you can start the server with "winswitch_server --debug-mode" to enable debugging.
