There is currently no provision to do it as part of a program-op, so you may have to do it manually between a load-op and a program-op, or as part of an image-dump-hook or image-restore-hook, contingent on a variable that gets reset (the image-dump-hook doesn't work on ECL, and you must use the ECL-specific epilogue instead; the image-dump-hook wastes a little bit of time at restart on other platforms). —♯ƒ • François-René ÐVB Rideau •Reflection&Cybernethics• http://fare.tunes.org The problem with socialism is that eventually you run out of other people's money. — Margaret Thatcher _______________________________________________ Asdf-devel mailing list Asdf-devel@common-lisp.net http://common-lisp.net/cgi-bin/mailman/listinfo/asdf-devel
