+ *
+ * Example of minimal program running under PAL.
+ *
+ * Run it using:
+ *   export PAL_DBG_CHANNELS="+all.all"
+ *   export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:..
+ *   ./example1
+ *
+ * With the PAL_DEBUG_CHANNELS environment variable set as above you
+ * should see a trace output when the program runs. Setting
+ * LD_LIBRARY_PATH is necessary unless you have installed librotor_pal.so in
+ * a standard location.
+ *
+ * Build notes :
+ * Since the PAL uses pthreads, some options must be passed to gcc to tell it
+ * to link against thread-safe versions of the standard libraries.
+ * On FreeBSD, use gcc -pthread
+ *
