+ * getopt_ext() is a rudimentary extension to getopt() to facilitate
+ * handling of long (wordier) option names.
+ *
+ * A long option is indicated by placing a "--" in front of the option
+ * name.
+ *
+ * Like getopt(), getopt_ext() also returns a single letter (actually an int)
+ * when an option is recognized. Therefore, the loop for processing long
+ * options and single letter options can be combined (see example in
+ * slapd/main.c)
+ *
+ * getopt_ext() first processes all the long options it can find. Currently,
+ * it does a "strcmp" to check for the validity of the option name (i.e.,
+ * the option name has to match exactly). 
+ *
+ * Once all the long options are handled, getopt_ext() uses getopt() to
+ * process the remaining options.
+ *
+ * getopt_ext() rearranges "argv" when it finds long options that it
+ * recognizes. The recognized options (and their parameters) are pushed
+ * to the end. 
+ *
+ * Single letter options are specified similar to getopt()
+ * Long options are specified using a list of "struct opt_ext". Each long
+ * option consists of string that identifies the option, a type that specifies
+ * if the option requires an argument and the single letter returned by
+ * getopt_ext() when the option is encountered. For example,
+ * {"verbose",ArgNone,'v'} specifies a long option (--verbose) that requires
+ * no arguments and for which, getopt_ext() returns a 'v' as the return value.
+ * {"instancedir",ArgRequired,'D'} specifies a long option (--instancedir dir)
+ * that requires an argument.
