It is not possible to specify two options from the same catagory (you'll get a
runtime error) to a single option. The CommandLine library specifies defaults
for all of these settings that are the most useful in practice and the most
common, which mean that you usually shouldn't have to worry about these.<p>

The miscellaneous option modifiers are the only flags where you can specify more
than one flag from the set: they are not mutually exclusive. These flags
specify boolean properties that modify the option.<p>

<a name="cl::CommaSeparated">The <b><tt>cl::CommaSeparated</tt></b> modifier
indicates that any commas specified for an option's value should be used to
split the value up into multiple values for the option. For example, these two
options are equivalent when <tt>cl::CommaSeparated</tt> is specified:
"<tt>-foo=a -foo=b -foo=c</tt>" and "<tt>-foo=a,b,c</tt>". This option only
makes sense to be used in a case where the option is allowed to accept one or
more values (i.e. it is a <a href="#cl::list">cl::list</a> option).<p>

So far, the only miscellaneous option modifier is the
