Initial kenv(1) hack for dumping the kernel environment. This can be used to extract modified boot hints to make loader(8)-time changes "sticky". It tries to use \ style quoting so that it can be used directly with foo.conf files. It can also extract specific variables. 2000-07-08 08:33:40 +00:00			`.\"`
