with a = (equal),

Long option flags can either be specified as they are
252

or with an (boolean parsable) option

.Pf ( Fl -help= Ns Ar yes ,

.Fl -help= Ns Ar true ,

.Pf ( Fl Fl help= Ns Ar yes ,

or similar), or they can also be negated
258
.Fl Fl help= Ns no ) ,

and if you're really confused you can do it multiple times
