+ *  stress-buffer tool makes infinite calls using read() for
+ *  any device specified by the command argument.
+ *
+ *  The size of buffer shall be a random number from 0 up to 1000.
+ *
+ *  Also is automatically created a file called: stats-M-D-Y-h-m-s.txt
+ *  in current directory with data executed.
+ *
+ *  The stress test is performed by several read() calls,
+ *  and it helped to identify real issues like:
+ *
+ *  - memory leaks
+ *  - specific crashs that are rare and hard to reproduce
+ *
+ *  To compile:
+ *             gcc -o stress-buffer stress-buffer.c -Wall
+ *
+ *  To execute:
+ *             ./stress-buffer /dev/device_for_test
+ *
+ *  Example:
+ *             ./stress-buffer /dev/video0
