            <c>=</c> specifies a

            If neither <c>=</c> nor <c>:</c> is not specified, then

            The value specifier may be used anywhere within 
            <paramref name="prototype" />, so <c>n|name=</c>, <c>n=|name</c> 
            and <c>n=|name=</c> are equivalent, but you cannot mix types;

            A default handler may be specified by using <c>&lt;&gt;</c> as the

            Multiple values may be bundled together, such as 
            <c>-opt key=value</c>.  The value separator list specifies which
            characters can be used to split the value argument to generate
            separate values.  The value separator list is available when 
            <paramref name="maxValueCount" /> is greater than <c>1</c>, and
            and an <see cref="T:Mono.Options.OptionValueType" /> was
            specified.  The value separator list follows the <c>=</c> or

          </para><list type="bullet"><item><term><para>
                A sequence of character enclosed by <c>{</c> and <c>}</c>.

                The sequence <c>{}</c> requires that each value be a different 
                argument, and no argument splitting will be performed.
                This sequence has no effect if other separators are also
                listed (as separate arguments are always permitted for
                <see cref="F:Mono.Options.OptionValueType.Required" />
                values).

            For example, the prototype <c>"A:+-*/"</c> would permit any of
            `<c>+</c>', `<c>-</c>', `<c>*</c>', or `<c>/</c>' to be used to
            split an argument into values, so <c>-A:5/2</c> would generate the
            sequence of values <c>5</c> and <c>2</c> for the option <c>-A</c>.
            Furthermore, the prototype <c>"A={--&gt;}{=&gt;}"</c> would permit
            either the string <c>--&gt;</c> or the string <c>=&gt;</c> to be used,
            so <c>-A A-&gt;B C</c> woud parse <c>A-&gt;B</c> as one value and

            <c>C</c> would be unhandled (unless the option required 3 values,
