+The miscellaneous option modifiers are the only flags where you can specify more

+<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

+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
