+----------------------------------------
+
+NOTE! The primary reason for the GPL/LGPL "dual licensing" for the library is
+that on UNIX-like systems, wimlib can optionally be linked to the third-party
+library "libntfs-3g", which is licensed GPLv2+.  Under some interpretations of
+the GPL, this would require that wimlib be licensed under the GPL as well.
 However, a binary copy of wimlib that was compiled without libntfs-3g support
-need not be affected by the libntfs-3g license (for example).
+(for example; the exception may be applicable in other situations as well)
+logically cannot be affected by libntfs-3g's license and should therefore be
+free to be redistributed under the LGPL instead of the GPL.
