+/**

+ * @brief Command to fill a file with a pattern.
+ *
+ * The written pattern is a simple 32 bit counter which makes it easy to find
+ * problems where buffers are not written to the correct location or where some
+ * blocks are missing.
+ *
+ * This file can be either compiled as part of RTEMS or as a stand alone Linux
+ * or (most likely) FreeBSD application. To compile it as stand alone, just use
+ * "gcc pattern-test.c"
