Update of /project/elephant/cvsroot/elephant
In directory clnet:/tmp/cvs-serv5313
Modified Files:
CREDITS INSTALL NEWS README TODO ele-bdb.asd elephant.asd
Removed Files:
Makefile config.lisp
Log Message:
Removed config.lisp and all Makefile related build options. The build is
now entirely driven from the elephant.asd and ele-bdb.asd files with a
simple user customization file, config.sexp, that should be copied to
my-config.sexp and customized to the user's environment. Thanks to
pinterface for the initial patch supporting this approach. Foreign
library loading is also controlled from the asd files now at system
load time rather than at compile time.

Under Un*x, you may actually already have this installed, though
it may be compiled with funny options, so if things don't work
you may want to try to start from scratch. FreeBSD has a port
