They are likely just loopholes that the copyright holder does not intend, but I'd love to see fixed. 1) identified in all material mentioning or referencing this software. Clearly this is outside the control of the licensee - some third party could mention or reference this software, causing you to violate the license. 2) do not contain misleading author or version information. This is a very wide net, and if such information is part of the api (so the license disallows spoofing), is non-free. This gets us into the weird situation where the work itself is free, but there are some modifications that are allowed by the license but would be non-free due to tripping a license provision. Aside from that, misleading is a vague term, which will be interpreted differently every time the question is asked. Also, what about pseudonymous modifications? -- Mark Rafn[EMAIL PROTECTED]http://www.dagon.net/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble?

Yeah, it isn't, because under copyright law you don't *need* a license in order to use a copy of the work.

Agreed. It's fine to say that the package must be labelled as to modifications made, but this phrasing seems to open the door to api-level requirements (like the filename or in-code version string cannot be misleading, whatever that means). -- Mark Rafn[EMAIL PROTECTED]http://www.dagon.net/ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.
