+=head1 NAME
+
+openssl-prime - compute prime numbers
+
+=head1 SYNOPSIS
+
+B<openssl prime>
+[B<-help>]
+[B<-hex>]
+[B<-generate>]
+[B<-bits> I<num>]
+[B<-safe>]
+[B<-checks> I<num>]
+[I<number> ...]
+
+=head1 DESCRIPTION
+
+This command checks if the specified numbers are prime.
+
+If no numbers are given on the command line, the B<-generate> flag should
+be used to generate primes according to the requirements specified by the
+rest of the flags.
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-help>
+
+Display an option summary.
+
+=item B<-hex>
+
+Generate hex output.
+
+=item B<-generate>
+
+Generate a prime number.
+
+=item B<-bits> I<num>
+
+Generate a prime with I<num> bits.
+
+=item B<-safe>
+
+When used with B<-generate>, generates a "safe" prime. If the number
+generated is I<n>, then check that C<(I<n>-1)/2> is also prime.
+
+=item B<-checks> I<num>
+
+This parameter is ignored.
