-The following paragraph is informational only.  The above exception is known to

-On UNIX-like systems, wimlib can optionally be compiled with libntfs-3g support.
-However, a binary copy of wimlib that was compiled without libntfs-3g support
-need not be affected by the libntfs-3g license (for example).

+--------------------------------------------------------------------------------
+
+NOTE! The reason for the "when not prohibited by a third-party software license"
+condition on the LGPL option for libwim is that libwim can optionally be linked
+to the third-party library "libntfs-3g", which is licensed under the GPL.
+Usually the GPL is interpreted in a way that means that any binary that uses a
+GPL library must be licensed under the GPL as well, not (for example) the LGPL.
+
+Therefore, if your build of libwim links to libntfs-3g, then you can't choose
+the LGPL option.  You may choose the LGPL option for Windows builds of libwim,
+since they don't link to libntfs-3g.  Likewise, you may choose the LGPL option
+for UNIX builds of libwim that were built with './configure --without-ntfs-3g'.
