* The default configuration file is now ~/.gnupg/gpg.conf. If an
old ~/.gnupg/options is found it will still be used. This
change is required to have more consistent naming scheme with

change is required to have a more consistent naming scheme with
forthcoming tools.
* The configure option --with-static-rnd=auto allows to build gpg
with all available entropy gathering modules included. At
runtime the best usable one will be selected from the list
linux, egd, unix.

linux - Use the module which accesses /dev/random.
This is the first choice and the default one
for GNU/Linux or *BSD.
auto - Compile linux, egd and unix in and
automagically select at runtime.
--with-egd-socket=<name>
This is only used when EGD is used as random
gatherer. GnuPG uses by default "~/.gnupg/entropy"
