### 5.4 Configuration files

There are a few configuration files to control certain aspects of `scdaemons`'s operation. Unless noted, they are expected in the current home directory (see option –homedir).

`scdaemon.conf`
  This is the standard configuration file read by `scdaemon` on startup. It may contain any valid long option; the leading two dashes may not be entered and the option may not be abbreviated. This default name may be changed on the command line (see option –options).
`scd-event`
  If this file is present and executable, it will be called on veyer card reader's status changed. An example of this script is provided with the distribution
`reader_n.status`
  This file is created by `sdaemon` to let other applications now about reader status changes. Its use is now deprecated in favor of `scd-event`.
