/**
* Constructor initializes the command line to be parsed. All information
* for parsing must be supplied to this constructor.
*
* @param argc The number of @a argv elements to parse.
* @param argv Command line tokens, such as would be passed
* to @c main().
* @param optstring Nul-terminated string containing the legitimate
* short option characters. A single colon ":"
* following an option character means the option
* requires an argument. A double colon "::" following
* an option character means the argument is optional.
* The argument is taken from the rest of the current
* @a argv element, or from the following @a argv
* element (only valid for required arguments;
* optional arguments must always reside in the same
* @a argv element). The argument value, if any is
* returned by the @c opt_arg() method.
* @a optstring can be extended by adding long options
* with corresponding short options via the
* @c long_option() method. If the short option
* already appears in @a optstring, the argument
* characteristics must match, otherwise it is added.
* See @c long_option() for more information.
* If 'W', followed by a semi-colon ';' appears in
* @a optstring, then any time a 'W' appears on the
* command line, the following argument is treated as
* a long option. For example, if the command line
* contains "program -W foo", "foo" is treated as a
* long option, that is, as if "program --foo" had
* been passed.
* The following characters can appear in @a optstring
* before any option characters, with the described
* effect:
* - '+' changes the @a ordering to @a REQUIRE_ORDER.
* - '-' changes the @a ordering to @a RETURN_IN_ORDER.
* - ':' changes the return value from @c operator()
* and get_opt() from '?' to ':' when an option
* requires an argument but none is specified.
*
* @param skip_args Optional (default 1). The specified number of
* initial elements in @a argv are skipped before
* parsing begins. Thus, the default prevents
* @a argv[0] (usually the command name) from being
* parsed. @a argc includes all @a argv elements,
* including any skipped elements.
* @param report_errors Optional, if non-zero then parsing errors cause
* an error message to be displayed from the
* @c operator() method before it returns. The
* error message is suppressed if this argument is 0.
* This setting also controls whether or not an error
* message is displayed in @c long_option() encounters
* an error.
* @param ordering Optional (default is @c PERMUTE_ARGS); determines
* how the @a argv elements are processed. This argument
* is overridden by two factors:
* -# The @c POSIXLY_CORRECT environment variable. If
* this environment variable is set, the ordering
* is changed to @c REQUIRE_ORDER.
* -# Leading characters in @a optstring (see above).
* Any leading ordering characters override both
* the @a ordering argument and any effect of the
* @c POSIXLY_CORRECT environment variable.
* @param long_only Optional. If non-zero, then long options can be
* specified using a single '-' on the command line.
* If the token is not a long option, it is processed
* as usual, that is, as a short option or set of
* short options.
*
* Multiple short options can be combined as long as only the last
* one can takes an argument. For example, if @a optstring is defined as
* @c "abc:" or @c "abc::" then the command line @e "program -abcxxx" short
* options @e a, @e b, and @e c are found with @e "xxx" as the argument for
* @e c.
* However, if the command line is specified as @e "program -acb" only
* options @e a and @e c are found with @e "b" as the argument for @e c.
* Also, for options with optional arguments, that is, those followed by
* "::", the argument must be in the same @a argv element, so "program -abc
* xxx" will only find "xxx" as the argument for @e c if @a optstring is
* specified as @c "abc:" not @c "abc::".

* it starts with "--" followed by other characters it is treated as

* @retval 0 A long option was found
