     20 =head1 DESCRIPTION
     21 
     22 This command checks if the specified numbers are prime.
     23 
     24 If no numbers are given on the command line, the B<-generate> flag should
     25 be used to generate primes according to the requirements specified by the
     26 rest of the flags.

     28 =head1 OPTIONS
     29 
     30 =over 4
     31 
     32 =item B<-help>
     33 
     34 Display an option summary.
     35 
     36 =item B<-hex>
     37 
     38 Generate hex output.
     39 
     40 =item B<-generate>
     41 
     42 Generate a prime number.
     43 
     44 =item B<-bits> I<num>
     45 
     46 Generate a prime with I<num> bits.
     47 
     48 =item B<-safe>
     49 
     50 When used with B<-generate>, generates a "safe" prime. If the number
     51 generated is I<n>, then check that C<(I<n>-1)/2> is also prime.
