[OpenFontLibrary] Expat License

[Karl Berry]

    Since it has an advertising clause, it's kinda like the unmodified BSD  
    license. 

Wrong.  Expat (and many other licenses) say that a certain name must
*not* be used in advertising.  That is ok.  The unmodified BSD was
GPL-incompatible because it said a certain name must actively *be* used,
which constitutes a "further restriction".  The passive "name must not
be used" does not.

Read the GPL FAQ and license-list for more details.
