-/**
- * @file
- *
- * This file contains functionality for identifying clients by various
- * means. The primary purpose of identification is to simply aid in
- * finding out which clients are using X server and how they are using
- * it. For example, it's often necessary to monitor what requests
- * clients are executing (to spot bad behaviour) and how they are
- * allocating resources in X server (to spot excessive resource
- * usage).
- *
- * This framework automatically allocates information, that can be
- * used for client identification, when a client connects to the
- * server. The information is freed when the client disconnects. The
- * allocated information is just a collection of various IDs, such as
- * PID and process name for local clients, that are likely to be
- * useful in analyzing X server usage.
- *
- * Users of the framework can query ID information about clients at
- * any time. To avoid repeated polling of IDs the users can also
- * subscribe for notifications about the availability of ID
- * information. IDs have been allocated before ClientStateCallback is
- * called with ClientStateInitial state. Similarly the IDs will be
- * released after ClientStateCallback is called with ClientStateGone
- * state.

+/**
+ * @file
+ *
+ * This file contains functionality for identifying clients by various
+ * means. The primary purpose of identification is to simply aid in
+ * finding out which clients are using X server and how they are using
+ * it. For example, it's often necessary to monitor what requests
+ * clients are executing (to spot bad behaviour) and how they are
+ * allocating resources in X server (to spot excessive resource
+ * usage).
+ *
+ * This framework automatically allocates information, that can be
+ * used for client identification, when a client connects to the
+ * server. The information is freed when the client disconnects. The
+ * allocated information is just a collection of various IDs, such as
+ * PID and process name for local clients, that are likely to be
+ * useful in analyzing X server usage.
+ *
+ * Users of the framework can query ID information about clients at
+ * any time. To avoid repeated polling of IDs the users can also
+ * subscribe for notifications about the availability of ID
+ * information. IDs have been allocated before ClientStateCallback is
+ * called with ClientStateInitial state. Similarly the IDs will be
+ * released after ClientStateCallback is called with ClientStateGone
+ * state.
