They document the API of the library, so you get into the API copyright issue, too. The argument given here by RMS' law instructor at Columbia is that run-time linking is a device to circumvent the copyright of the library, which otherwise would be static-linked and explicitly copied. Given the universality of run-time linking, I think there's a good counter-argument that it's a device for copyright evasion rather than more pragmatic goals. Thanks Bruce
