+/*! \mainpage libosmovty Documentation
+ *
+ * \section sec_intro Introduction
+ * This library is a collection of common code used in various
+ * GSM related sub-projects inside the Osmocom family of projects.  It
+ * has been imported/derived from the GNU Zebra project.
+ * \n\n
+ * libosmovty implements the interactive command-line on the VTY
+ * (Virtual TTY) as well as configuration file parsing.
+ * \n\n
+ * Please note that C language projects inside Osmocom are typically
+ * single-threaded event-loop state machine designs.  As such,
+ * routines in libosmovty are not thread-safe.  If you must use them in
+ * a multi-threaded context, you have to add your own locking.
