*** The performance of the UNIX random gatherer module is not very good
*** and it does not keep the entropy pool over multiple invocations of
*** GnuPG. The suggested way to overcome this problem is to use the
***
*** Entropy Gathering Daemon (EGD)
***
*** which provides a entropy source for the whole system. It is written
*** in Perl and available at the GnuPG FTP servers. For more information
*** consult the GnuPG webpages:
***
*** http://www.gnupg.org/download/#EGD
***
*** You may want to run ./configure with --enable-static-rnd=egd or
*** --enable-static-rnd=auto to use it.
