+/*
+ * AnyOption 1.3
+ *
+ * kishan at hackorama dot com www.hackorama.com JULY 2001
+ *
+ * + Acts as a common facade class for reading
+ * commandline options as well as options from
+ * an optionfile with delimited type value pairs
+ *
+ * + Handles the POSIX style single character options ( -w )
+ * as well as the newer GNU long options ( --width )
+ *
+ * + The option file assumes the traditional format of
+ * first character based comment lines and type value
+ * pairs with a delimiter , and flags which are not pairs
+ *
+ * # this is a coment
+ * # next line is an option value pair
+ * width : 100
+ * # next line is a flag
+ * noimages
+ *
+ * + Supports printing out Help and Usage
+ *
+ * + Why not just use getopt() ?
+ *
+ * getopt() Its a POSIX standard not part of ANSI-C.
+ * So it may not be available on platforms like Windows.
+ *
+ * + Why it is so long ?
+ *
+ * The actual code which does command line parsing
+ * and option file parsing are done in few methods.
+ * Most of the extra code are for providing a flexible
+ * common public interface to both a resourcefile and
+ * and command line supporting POSIX style and
+ * GNU long option as well as mixing of both.
+ *
+ * + Please see "anyoption.h" for public method descriptions
+ *

+/* Updated Auguest 2004
+ * Fix from Michael D Peters (mpeters at sandia.gov)
+ * to remove static local variables, allowing multiple instantiations
+ * of the reader (for using multiple configuration files). There is
+ * an error in the destructor when using multiple instances, so you
+ * cannot delete your objects (it will crash), but not calling the
+ * destructor only introduces a small memory leak, so I
+ * have not bothered tracking it down.
+ *
+ * Also updated to use modern C++ style headers, rather than
+ * depricated iostream.h (it was causing my compiler problems)
+*/
+
+/*
+ * Updated September 2006
+ * Fix from Boyan Asenov for a bug in mixing up option indexes
+ * leading to exception when mixing different options types
