RAND_egd() queries the entropy gathering daemon EGD on socket B<path>.
-=head1 RETURN VALUES
+EGD is available from http://www.lothar.com/tech/crypto/ (C<perl
+Makefile.PL; make; make install> to install). It is run as B<egd>
+I<path>, where I<path> is an absolute path designating a socket. When
+RAND_egd() is called with that path as an argument, it tries to read
+random bytes that EGD has collected.
