+Frequently Asked Questions about the SANE licensing:
+
+  * Why don't you use the GNU LPGL ?
+
+    The reason SANE isn't licensed under the GNU LGPL is very simple: the
+    GNU LGPL didn't exist at the time SANE was first released. So, the SANE
+    Exception was added to the GNU GPL.
+
+  * Why don't you relicense SANE, now that the GNU LGPL is available ?
+
+    To relicense the various pieces of code composing SANE, each and every
+    copyright holder needs to agree with the relicensing. Unfortunately, some
+    of the (original) backend authors cannot be contacted any longer, for
+    various reasons; not to mention each and every contributor who sent in a
+    patch. This effectively makes it impossible for the SANE Project to
+    relicense SANE.
