+ * \brief Command line parser.
+ *
+ * The command line parser can extract certain data fields out of a character
+ * string and assign values to variables. It has 2 main functions. One to parse
+ * a command line in the form of standard C runtime "argc" and "argv" parameters,
+ * and the other to assemble these parameters reading text lines from a file in
+ * case the C runtime does not provide them.
