Take a look > at the loader.conf(5) for example. ok, but all we need to say is the following: The file can contain lines of the form name = "value" # this is a coment where whitespace around name and '=' is ignored, and so is everything after a '#' character. Almost any printable character except '=' is acceptable as part of a name. Quotes are optional and necessary only if the value contains whitespace. so why don't we just say that in the kenv(1) manpage (and refer to that) instead of referring to loader.conf which contains a lot of stuff that does not apply in this case ? cheers luigi
