 #      The license of the package.

-#      Sometimes licensing is other than a single text file.  See
-#      doc/TODO for discussion of how to handle packages with dual
-#      licensing (a choice) or where multiple licenses apply
-#      simultaneously.

+#      Dual licenses can be specified with OR expressions:
+#      LICENSE=        license1 OR license2
+#
+#      If more than one license applies at the same time, AND expressions
+#      can be used:
+#      LICENSE=        license1 AND license2
+#
+#      Expressions can be nested if necessary:
+#      LICENSE=        (license1 AND license2) OR license3
+#      Parenthesis are required when mixing AND and OR.
+#
 #      Every package should specify its license.  (Prior to early 2009,
 #      Open Source and Free software did not have license tags.)
