-=item [B<-help>]
+=item B<-help>
Display an option summary.
-=item [B<-hex>]
+=item B<-hex>
Generate hex output.
-=item [B<-generate>]
+=item B<-generate>
Generate a prime number.
-=item [B<-bits num>]
+=item B<-bits> I<num>
Generate a prime with B<num> bits.
-=item [B<-safe>]
+=item B<-safe>
When used with B<-generate>, generates a "safe" prime. If the number
generated is B<n>, then check that B<(n-1)/2> is also prime.
-=item [B<-checks num>]
+=item B<-checks> I<num>
Perform the checks B<num> times to see that the generated number
is prime. The default is 20.
