=item B<-bits> I<num>
-Generate a prime with B<num> bits.
+Generate a prime with I<num> bits.
=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.
+generated is I<n>, then check that C<(I<n>-1)/2> is also prime.
=item B<-checks> I<num>
-Perform the checks B<num> times to see that the generated number
+Perform the checks I<num> times to see that the generated number
