+ * @class ACE_Argv_Type_Converter
+ *
+ * @brief To convert 'char' input/command line parameter to 'wchar_t'.
+ *
+ * This class is to convert 'char' type command line paramter to
+ * wide-character (wchar_t) format and stores the copy of it.
+ * This is useful for all classes that use 'char**' argv but cannot
+ * be converted into 'ACE_TCHAR**' version.
+ * Note that the converted data will be lost upon destruction, so
+ * classes should use this class as their data member.
