+FAT Long File Names
+^^^^^^^^^^^^^^^^^^^
+
+  NOTE:  If CONFIG_FAT_LFN is defined in your NuttX configuration file, then
+  there may be some legal, patent issues. The following was extracted from
+  the entry "File Allocation Table from Wikipedia, the free encyclopedia:
+
+    "On December 3, 2003 Microsoft announced it would be offering licenses
+     for use of its FAT specification and 'associated intellectual property',
+     at the cost of a US$0.25 royalty per unit sold, with a $250,000 maximum
+     royalty per license agreement.
+
+     o "U.S. Patent 5,745,902 (http://www.google.com/patents?vid=5745902) -
+        Method and system for accessing a file using file names having
+        different file name formats. ...
+     o "U.S. Patent 5,579,517 (http://www.google.com/patents?vid=5579517) -
+        Common name space for long and short filenames. ...
+     o "U.S. Patent 5,758,352 (http://www.google.com/patents?vid=5758352) -
+        Common name space for long and short filenames. ...
+     o "U.S. Patent 6,286,013 (http://www.google.com/patents?vid=6286013) -
+        Method and system for providing a common name space for long and
+        short file names in an operating system. ...
+ 
+    "Many technical commentators have concluded that these patents only cover
+     FAT implementations that include support for long filenames, and that
+     removable solid state media and consumer devices only using short names
+     would be unaffected. ..."
+ 
+  So you have been forewarned:  Use the long filename at your own risk!
+
+uIP
+^^^
+
+Many lower-level networking components of NuttX derive from uIP which
+has a similar BSD style license:

+   All rights reserved.
+
+IGMP
+^^^^

+IGMP support, if enabled in uIP, adds additional logic by Steve Reynolds:

+dtoa():
+^^^^^^
+
+  If you enable floating point conversions with CONFIG_LIBC_FLOATINGPOINT,
+  then some files with an unmodified BSD license will be included.  That
+  license is similar to the above (modified) BSD license, but has an
+  additional requirement that I state the following:
+
+  "This product includes software developed by the University of
+   California, Berkeley and its contributors."
