+Each file in SLIB (over a dozen lines in length) is either in the public
+domain, or comes with a statement of terms permitting users to copy,
+modify, and redistribute it.
+
+The comments at the beginning each file (containing over a dozen lines)
+must specify its terms.  For instance, the comments at the beginning of
+"Template.scm" declare that it is in the public domain:
+
+  ;;; "Template.scm" configuration template of *features* for Scheme
+  ;;; Author: Aubrey Jaffer
+  ;;;
+  ;;; This code is in the public domain.
+
+Each copyrighted file lists the names of the copyright holders and gives
+permissions to copy, modify, and redistribute the file.  For instance,
+the beginning of "require.scm" states:
