+/**
+ * <p>Parses command line arguments, using a syntax that attempts to take from the best of POSIX {@code getopt()}
+ * and GNU {@code getopt_long()}.</p>
+ *
+ * <p>This parser supports short options and long options.</p>
+ *
+ * <ul>
+ *   <li><dfn>Short options</dfn> begin with a single hyphen ("<kbd>-</kbd>") followed by a single letter or digit,
+ *   or question mark ("<kbd>?</kbd>"), or dot ("<kbd>.</kbd>").</li>
+ *
+ *   <li>Short options can accept single arguments. The argument can be made required or optional. The option's
+ *   argument can occur:
+ *     <ul>
+ *       <li>in the slot after the option, as in <kbd>-d /tmp</kbd></li>
+ *       <li>right up against the option, as in <kbd>-d/tmp</kbd></li>
+ *       <li>right up against the option separated by an equals sign (<kbd>"="</kbd>), as in <kbd>-d=/tmp</kbd></li>
+ *     </ul>
+ *   To specify <em>n</em> arguments for an option, specify the option <em>n</em> times, once for each argument,
+ *   as in <kbd>-d /tmp -d /var -d /opt</kbd>; or, when using the
+ *   {@linkplain ArgumentAcceptingOptionSpec#withValuesSeparatedBy(char) "separated values"} clause of the "fluent
+ *   interface" (see below), give multiple values separated by a given character as a single argument to the
+ *   option.</li>
+ *
+ *   <li>Short options can be clustered, so that <kbd>-abc</kbd> is treated as <kbd>-a -b -c</kbd>. If a short option
+ *   in the cluster can accept an argument, the remaining characters are interpreted as the argument for that
+ *   option.</li>
+ *
+ *   <li>An argument consisting only of two hyphens (<kbd>"--"</kbd>) signals that the remaining arguments are to be
+ *   treated as non-options.</li>
+ *
+ *   <li>An argument consisting only of a single hyphen is considered a non-option argument (though it can be an
+ *   argument of an option). Many Unix programs treat single hyphens as stand-ins for the standard input or standard
+ *   output streams.</li>
+ *
+ *   <li><dfn>Long options</dfn> begin with two hyphens (<kbd>"--"</kbd>), followed by multiple letters, digits,
+ *   hyphens, question marks, or dots. A hyphen cannot be the first character of a long option specification when
+ *   configuring the parser.</li>
+ *
+ *   <li>You can abbreviate long options, so long as the abbreviation is unique.</li>
+ *
+ *   <li>Long options can accept single arguments.  The argument can be made required or optional.  The option's
+ *   argument can occur:
+ *     <ul>
+ *       <li>in the slot after the option, as in <kbd>--directory /tmp</kbd></li>
+ *       <li>right up against the option separated by an equals sign (<kbd>"="</kbd>), as in
+ *       <kbd>--directory=/tmp</kbd>
+ *     </ul>
+ *   Specify multiple arguments for a long option in the same manner as for short options (see above).</li>
+ *
+ *   <li>You can use a single hyphen (<kbd>"-"</kbd>) instead of a double hyphen (<kbd>"--"</kbd>) for a long
+ *   option.</li>
+ *
+ *   <li>The option <kbd>-W</kbd> is reserved.  If you tell the parser to {@linkplain
+ *   #recognizeAlternativeLongOptions(boolean) recognize alternative long options}, then it will treat, for example,
+ *   <kbd>-W foo=bar</kbd> as the long option <kbd>foo</kbd> with argument <kbd>bar</kbd>, as though you had written
+ *   <kbd>--foo=bar</kbd>.</li>
+ *
+ *   <li>You can specify <kbd>-W</kbd> as a valid short option, or use it as an abbreviation for a long option, but
+ *   {@linkplain #recognizeAlternativeLongOptions(boolean) recognizing alternative long options} will always supersede
+ *   this behavior.</li>
+ *
+ *   <li>You can specify a given short or long option multiple times on a single command line. The parser collects
+ *   any arguments specified for those options as a list.</li>
+ *
+ *   <li>If the parser detects an option whose argument is optional, and the next argument "looks like" an option,
+ *   that argument is not treated as the argument to the option, but as a potentially valid option. If, on the other
+ *   hand, the optional argument is typed as a derivative of {@link Number}, then that argument is treated as the
+ *   negative number argument of the option, even if the parser recognizes the corresponding numeric option.
+ *   For example:
+ *   <pre><code>
+ *     OptionParser parser = new OptionParser();
+ *     parser.accepts( "a" ).withOptionalArg().ofType( Integer.class );
+ *     parser.accepts( "2" );
+ *     OptionSet options = parser.parse( "-a", "-2" );
+ *   </code></pre>
+ *   In this case, the option set contains <kbd>"a"</kbd> with argument <kbd>-2</kbd>, not both <kbd>"a"</kbd> and
+ *   <kbd>"2"</kbd>. Swapping the elements in the <em>args</em> array gives the latter.</li>
+ * </ul>
+ *
+ * <p>There are two ways to tell the parser what options to recognize:</p>
+ *
+ * <ol>
+ *   <li>A "fluent interface"-style API for specifying options, available since version 2. Sentences in this fluent
+ *   interface language begin with a call to {@link #accepts(String) accepts} or {@link #acceptsAll(Collection)
+ *   acceptsAll} methods; calls on the ensuing chain of objects describe whether the options can take an argument,
+ *   whether the argument is required or optional, to what type arguments of the options should be converted if any,
+ *   etc. Since version 3, these calls return an instance of {@link OptionSpec}, which can subsequently be used to
+ *   retrieve the arguments of the associated option in a type-safe manner.</li>
+ *
+ *   <li>Since version 1, a more concise way of specifying short options has been to use the special {@linkplain
+ *   #OptionParser(String) constructor}. Arguments of options specified in this manner will be of type {@link String}.
+ *   Here are the rules for the format of the specification strings this constructor accepts:
+ *
+ *     <ul>
+ *       <li>Any letter or digit is treated as an option character.</li>
+ *
+ *       <li>An option character can be immediately followed by an asterisk (*) to indicate that the option is a
+ *       "help" option.</li>
+ *
+ *       <li>If an option character (with possible trailing asterisk) is followed by a single colon (<kbd>":"</kbd>),
+ *       then the option requires an argument.</li>
+ *
+ *       <li>If an option character (with possible trailing asterisk) is followed by two colons (<kbd>"::"</kbd>),
+ *       then the option accepts an optional argument.</li>
+ *
+ *       <li>Otherwise, the option character accepts no argument.</li>
+ *
+ *       <li>If the option specification string begins with a plus sign (<kbd>"+"</kbd>), the parser will behave
+ *       "POSIX-ly correct".</li>
+ *
+ *       <li>If the option specification string contains the sequence <kbd>"W;"</kbd> (capital W followed by a
+ *       semicolon), the parser will recognize the alternative form of long options.</li>
+ *     </ul>
+ *   </li>
+ * </ol>
+ *
+ * <p>Each of the options in a list of options given to {@link #acceptsAll(Collection) acceptsAll} is treated as a
+ * synonym of the others.  For example:
+ *   <pre>
+ *     <code>
+ *     OptionParser parser = new OptionParser();
+ *     parser.acceptsAll( asList( "w", "interactive", "confirmation" ) );
+ *     OptionSet options = parser.parse( "-w" );
+ *     </code>
+ *   </pre>
+ * In this case, <code>options.{@link OptionSet#has(String) has}</code> would answer {@code true} when given arguments
+ * <kbd>"w"</kbd>, <kbd>"interactive"</kbd>, and <kbd>"confirmation"</kbd>. The {@link OptionSet} would give the same
+ * responses to these arguments for its other methods as well.</p>
+ *
+ * <p>By default, as with GNU {@code getopt()}, the parser allows intermixing of options and non-options. If, however,
+ * the parser has been created to be "POSIX-ly correct", then the first argument that does not look lexically like an
+ * option, and is not a required argument of a preceding option, signals the end of options. You can still bind
+ * optional arguments to their options using the abutting (for short options) or <kbd>=</kbd> syntax.</p>
+ *
+ * <p>Unlike GNU {@code getopt()}, this parser does not honor the environment variable {@code POSIXLY_CORRECT}.
+ * "POSIX-ly correct" parsers are configured by either:</p>
+ *
+ * <ol>
+ *   <li>using the method {@link #posixlyCorrect(boolean)}, or</li>
+ *
+ *   <li>using the {@linkplain #OptionParser(String) constructor} with an argument whose first character is a plus sign
+ *   (<kbd>"+"</kbd>)</li>
+ * </ol>
