+ * @brief Millisecond timer library header file.
+ *
+ * @section DESCRIPTION
+ *
+ * The mstimer library provides functions for setting, resetting and
+ * restarting timers, and for checking if a timer has expired. An
+ * application must "manually" check if its timers have expired; this
+ * is not done automatically.
+ *
+ * A timer is declared as a \c struct \c mstimer and all access to the
+ * timer is made by a pointer to the declared timer.
+ *
+ * Adapted from the Contiki operating system.
+ * Original Authors: Adam Dunkels <adam@sics.se>, Nicolas Tsiftes <nvt@sics.se>
